Press ESC to cancel. Esther Fleming September 24, Table of Contents. Previous Article What is special about Marquette University? Next Article How do rivers impact the economy? It was actually I who said the Kloppen system was useless, not Questioning the Data, who chose it as his system of reference. FYI — the driest place on earth is in the Antarctic — a polar desert.
I regret using the Koppen system in that reply because it has led to confusion. I was pressed for time at that moment, so just did a quick calculation. Also, if Antarctic is a desert, why is the snow accumulating over time!? One of the most extreme deserts in the world, these snow-free valleys harbour life, despite the hostile environment.
The Dry Valleys are ice-free, or dry, because any precipitation that falls as snow on the valley floor is blown away by strong, dry katabatic winds, through the process of sublimation.
Is that picture taken in summer or winter? I will take ownership for having opened conversation on this website in a somewhat inflammatory fashion. But I did really think soon afterwards that an intelligent exchange might ensue.
However, despite having provided numerous academic articles and scientific publications, the only responses I have received from this website are unsubstantiated opinions and childish insults. I will let those remarks stand as both a reflection of, and testament to, those who wrote them.
Please, and I sincerely mean this: continue your lives in peace. If you treat me, a harmless stranger, this way, I can only imagine how you treat those who are close to you, who can truly get under your skin. Hey Cagen, the Atacama Desert near the equator is actually on par with the dry valleys of Antarctica for the world driest place if all three components of: aridity, air moisture levels dewpoints , and ground moisture presence, are factored in equally.
This is the total environmental dryness of a location. But, both are Martian paradises for research on the red planet. One just happens to be relatively hot, and the other very cold! No the polar deserts are not. And even if the polar deserts were more dryer.
Who cares? Hot deserts are much more interesting and travel freindly. GO Accuweather!! Hello Again; I apologize to QTD, if my occasional obsessive passion may have just crossed an ethical boundary this most recent time. I will adhere to my more typical professional and helpful decor from here on out, when I chat or comment with you, Joe, and others.
Have a nice evening. To us humans the Atacama Sonoran Namib and Sahara is liveable there even if sparsely but who on earth could survive in a frigid polar deserts wasteland of ice and snow. To us it matters very little in our lives. Ashcroft or most any desert outside the poles has more significance and meaning for us living breathing people.
Wow, your logical and academically well informed retort has convinced me of the errors of my ways. I had never realised how childish insults can demonstrate true brilliance and insight. Thank you for this valuable lesson.
Then you get upset when you get poked at? Really, this is a regional opinion piece. This article only deals with the Canadian situation, which, when we crunch the numbers reveals that Ashcroft is the most arid place in Canada it has the highest moisture deficit in the country. Kudos Catherine being a nurse is a thankless difficult job and you need to be tough to do it.
My name is Dave. Have a lovely evening. I must spend some time studying more or figuring out more. Thanks for great information I used to be on the lookout for this info for my mission. Are the first 4 connected? Carcross is far away from the others. Bordering that desert is the Mojave Desert which extends halfway up Nevada and California.
Bordering that to the north is the Great Basin Desert which extends up to the Oregon border. Would you mind sharing a longer list of driest cities in BC?
How about this map? The list is in order from driest to wettest. You can click on the icons on the list on the left or on the map. This is based upon weather stations from to with at least 5 years of data. The list on the left is in order from driest to wettest. How about where are the mildest spots in BC. There must be a hidden valley in south western bc or on the islands or on vancouver island in sheltered from all the cold winds which produces a super micro or nano climate. Theres supposed to be a 7b zone in ontario but cant find any info.
In the McMurdo valleys, biologists did discover microscopic life forms upon further examination, but in this newly discovered location in the Atacama, it is an -absolute sterile zone. That aracama drier location intrigues me very much. So does low relative humidity. Hello Joe; how are you doing this evening? Yes, I am a substantial fan of low relative humidity as well.. Specifically I love the best warmest, sunniest, driest Canadian climate that we can find!
More about that in a minute. On rare occasions, the summer dewpoint in Ashcroft can drop below the freezing mark. Edmonton AB in the winter time —indoors! I have a ton of respect for them! Accu-W is also at least 20 times more massive as a corporation than is the weather network.
The reason why RH interests me so much is that i know what it feels like to work in humid conditions and it sucks. Even doing very little you sweat like a pig.. You should look at the humidity levels in southern iran or towns in the atacama. Extremely low less than 10percent constantly. Temperatures although have been over Degrees from late April to August basically. This short, potential, unusually humid period in the Southwest is called the monsoon period. In regards to Accuweather again Joe, you should educate friends, family, and everyone you can reach about how superior they are to TWN!
Have a good one buddy. That place in Nevada sounds like my new Buddy Adams lol Ill have to check it out. I think anything in the 30percent range in summer id call an ideal rh if it gets too hot then 20 percent and lower would be more comfy right? Id love to visit the Atacama one day. Do you knof a specific location in vancouver island or mainland that has the most pleasant year round weather.
With less rain less rainy days good enough weather to grow possibly citrus or subtropical plants.. Hey again Joe; I first just wanted to say that I have enjoyed our occasional interactions on this awesome blog page buddy! In the end, both the Atacama Desert core and The McMurdo valleys are profoundly dry, and make everywhere else; including -Buddy Adams- seem relatively damp.
The new location not far from Yungay just happens to take the crown! Lips and skin will be cracked etc. This is more like Ashcroft BC during heat waves. And even for —them— NOT when working physically hard!!! Welcome to Thailand during the rainy season.
It should be -their- site that you follow my man! Have a great night Joe, and I look forward to hearing from you again soon.
Tofino on the outer coast has —hardier PALM trees. It should be noted that peaches are not grown in Ashcroft because the winters are too cold. Cherries and apricots are fine, but peaches are touch and go. The arctic air flows out from the interior and no one can escape that on the mainland especially. There are certainly many places in the interior that do get a lot of Chinook winds in the winter.
Nemiah and Tatlayoko Lake areas in the west Chilcotin. It is important to remember that Canada and the US used two different methods to measure sunshine hours. The US method gives you an extra to hours. Canada stopped recording sunshine hours in about , so no recent data, but looking at the data you posted you can look at Windsor, ON and Detroit for eg.
Between Seattle and Vancouver there are only about hours more in Seattle. Basically, the Campbell-Stokes recorder Canada used needed bright sunshine, so if there was haze, smoke, light clouds, or late or early in the day, nothing would be recorded while it would be in the US. Thanks for the sunshine info. They probably shut down sunshine info because its a tedious and difficult process to gather that info. Alot of monitoring.
But im sure there must be new technology out there that will make it easier to collect daily monthly and yearly sunshine much easier. Theres supposed to be weather satellites out there collecting sunshine data. When Trudeau the 1st was in power followed by Mulroney, the government of Canada spent money like drunken sailors same was Trudeau the 2nd now , so the national debt became so unmanageable that Chretien had to make massive cuts to services including weather monitoring.
Huge cuts were made in and , and have never recovered. Hello Joe; intriguing contemplation regarding a potential dry, Ashcroft-esque type hidden valley in the center of Vancouver island buddy! Like you said, away from any arctic influences in the winter, BUT, also away from any wet marine influences from the Pacific itself all year round!
They like to think that -air masses- are the only things that matter, and to hell with geography. The Gulf Islands are relatively dry and mild. Not as dry as Ashcroft, but as dry as Vernon, and in the summer drier than anywhere else in Canada.
Do you have any easily accessible stats for Las Vegas? Both locales have profound moisture deficits that are quite alien given the mild to hot year round temperatures I suppose. Lots of places get far more precipitation in summer than Ashcroft including Osoyoos, Lytton, and Victoria.
When it comes to dew point and relative humidity, Ashcroft is lower than the others. Thanks any particular island which is ghe warmest and driest of them all? Gabriola island? I got some very interesting info about southeast vancouver island. Did you know its within the Olympic Mountains shadow? The gulf islands will be much much drier than Vancouver or the west coast of the Island, but still wetter than the dry places in the interior.
Totally agree. Geography can greatly mitigate weather. Like for example on side of a hill at meters above sea level is milder at night than at bottom of a valley where the cold air sinks down and damages sensitive plants. Micro and Nano climates intrigue me alot too. There must be dozens of them in sw bc and on the island only problem is that constant rain on the west part of the island and in southern bc.
Theres a very intriguing fact i stumbled accross on the net that affects seast vancouver island that i never heard anyone talk about. The Olympic mountains shadow. Summers are hot, as well as dry, with both low rainfall, and low RH; not quite as dry as Ashcroft but almost. The winter snowfall is meager, even less snow than both Ashcroft and Osoyoos. They can grow peaches, cherries, and apricots in Lillooet comfortably, and since the QTD officer said that Ashcroft is just a little too cold in the winter for peaches in most years, Lillooet is definitely enough milder to be comfortable with peaches.
Winter rainfall is -way- less than on the coast anywhere, even including the Cascade shadow locations. Finally Joe, the very hardiest breeds of palm trees can do OK in Lillooet easily for 9 months of the year;- however in the 3 coldest months of Dec.
Winter sunshine hours are the highest of anywhere in BC west of Revelstoke. I believe this just might be the place for you to move to when the time is right.
I hope this helps! Have a great evening. Hi Dave thanks very much. I will definitely check it it out. What did you think of the Olympic shadow link. Much appreciated. Glad you liked the info. Enjoy a super evening. Lillooet is by FAR the least snowy places in the BC interior, and is certainly much more mild in the winter than Ashcroft. However, it does get quite a lot of wind. Now, if you were to get out of the main valley, and live 15km away in Seton Portage, you get all the benefits of Lillooet plus no wind.
Thanks a Million QTD officer! Thank you Sirs. Im not a fan of constant strong winds. Going to look at Buddy Adam town in nv. Just looked up Mercury nv. I googled Maria Elena Town Chile weather. Even tho the temps are 27max and 9minimums.
Can you beleive there are people growing citrus outdoors in BC? Hi Joe; How are you doing this evening buddy? I took an in depth look at the Cascade shadow zone, and the process that was used to define the epicenter, and the boundaries etc. In virtually every other way, Victoria is pretty well a mirror image of the Lillooet climate….
Ultimately however, if it was me making a decision about where to live, I would attempt to live the 9 warm months in Liilooet or Ashcroft , and the 3 winter months in Victoria or Tofino , with 2 homes if possible. Have a great night Joe! Hope this helps. Hello QTD officer; how are you this evening? I had a follow up contemplation about the geographical alignment of the trench that Seton Portage lies within. This pair of circumstances would particularly explain the lack of wind in Seton Portage.
Enjoy the rest of the evening. Thank you very much. Thank you very much for the insights. Also too, a desert place called Mercury Nevada, although hot most of the year, is actually nearly as dry, in terms of the dewpoints, as the typical winter level in many Canadian locations! Average yearly dewpoint in Mercury: minus 9 degrees Celsius.
Five percent is quite common, and two percent is not unheard of. Great place for arthritis, but horrible for lips and skin. Temps over Degrees F are common in the summer as well. Finally, shutting down sunshine hours?? Sounds like Weather Network influence on Environment Canada! Have a good evening. C including Thompson river valley When I got to Churn creek it was partly sunny with just a small area around me a few miles wide that clouds would literally break up and reform on the other side of the Fraser I was there for 2 days with no rain When I left it poured from canoe creek all the way to Langley.
This is why: Ashcroft, by two separate climate systems, provided here by the QTD officers last year, has been unequivocally shown to classify as true warm desert although just barely. Does this sound about right to you Ian? Although this area is probably the one that QTD said some time ago, that someone fool hardily suggested received only TWO inches of annual precipitation, or less than Death Valley CA, it probably -does- only receive 5 or 6 inches.
The winters are short and mild, where with special attention, hardy breed palm trees can do ok. They receive the most winter sunshine west of Revelstoke. Churn Creek sounds, overall, just as good or better than Seton Portage! A gentleman named Joe I corresponded with this past summer, would likely be most intrigued by this revelation. Any website that I see again, that attempts to adamantly refute that Canada has a true warm desert -now- I will have to report to law enforcement.
Just kidding. Have a good one Ian. Cheers, Dave. Only problem with Churn Creek is theres no towns or cities for hundreds of kms and no info on winter temperatures with it being at I hope you have been keeping well my friend.
Churn Creek is apparently therefore, an even drier version of Ashcroft, with a similar year round temperature profile. I hope this helps!! At Just wondering. Hello Joe; things are good buddy! Thanks very much for asking! I will most certainly be back at it next spring!
Until then keep well, and have a very merry Christmas my friend! Great blog post. We moved to Ashcroft in July By, the middle of September, it had rained at least 18 times. Even in the hottest part of the summer, there is always 6 hours of cool, comfortable weather first thing in the morning 4AM to 10AM.
In the shade at 32C, for example, the air is so dry, it is very comfortable. Cheers to Joe as well! If you receive this; how are things buddy? My semester just wrapped up, and am back into my amateur love now! Hi Dave good to hear from you. Bc is an oven this summer. Someplace must have hit over 50c in the shade. Did you have a good winter? What have you been up to these days? Oh yes; our own back yard has been like the searing Sahara this past week eh?! I guess the dry heat must be incinerating my brain no doubt.
This crazy subsidence effect was keeping the air exceptionally dry. The extreme high temperatures also contributed to driving the relative humidity down as well.
Just for reference, plus 3 to 8 C is common for Ashcroft. Have an awesome evening my friend, it feels great having a slower pace from work over the summer! PS: there were NO official 50 C temps. Lytton just missed by less than half a degree I believe. Winter went by fast thankfully. Great to hear from you too. Glad your working and school went smoothly.
These torrid temps in bc are really great topic of conversation now. That low RH is insanely low for vernon they are of vegas and iranian desert porportions. Here in ontario muggy rainy humid lethargic feeling days.. I wanted the 50c you guys got lol. Yes, in regards to Muggy Ontario I absolutely hear you bud.
A ccording to the research of Junah Birchwater, the only true desert in British Columbia is a small patch of ground around Ashcroft. Canada has no true deserts, only regions that exhibit some desertlike features. The Okanagan Desert is the common name for a semi-arid shrubland located in the southern region of the Okanagan Valley in British Columbia and Washington. It is centred around the city of Osoyoos and is the only semi-arid shrubland in Canada….
Canada has only one officially, recognized desert.
