Hi Glacier,

What do you mean by AHCCD stations?

Glacier wrote:Environment Canada uses all the longer term weather stations in Canada to investigate climate change. They combine nearby stations and make adjustments if the locations were moved slightly or if the measurement methods changed slightly. This gives them far more weather stations in Canada, and thus makes it easier to determine how the climate is changing over time.

And YET, despite the combination of weather stations, there are now only 2 weather stations recording precipitation in the entire territories in their database, equally half of Canada's landmass, and only 101 stations in the entire country total, 40% of which are BC thanks to the high number of coastal lighthouse stations.

39 in BC; 22 in Quebec, 12 in Ontario, 7 in Saskatchewan, 6 in Manitoba, 4 in Newfoundland & Labrador, 4 in Alberta, 3 in Nova Scotia, 2 in Nunavut, 2 in New Brunswick, 0 in the Yukon, 0 in the Northwest Territories, and 0 in Prince Edward Island.

Look at the decrease after 2007 when the federal conservatives made massive cuts to EC... not that Mr. Selfie is doing anything to reverse that.

Ya, it seems that since 1995 both Liberal and Conservative governments have been making huge cuts to Environment Canada. I think the 2007 drop has more to do with the fact that Environment Canada no longer conducts quality control checks on the volunteer weather station data. More major station changes came around 2012 when they contracted out most of the airport weather data was transferred to Nav Canada, and Nav Canada does not have the same interest in maintain records; they're more interested in current conditions.

The biggest cuts came in 1995, 2001, and 2005, but the number of stations weren't impacted as much as you'd think because most of the stations were still manual volunteer ones. It's the automation and centralization that's really led to the biggest drop data collection. Basically, there used to be 100s of Environment Canada employees collecting data all over the country, but the closed the offices in Kamloops and then Kelowna and then Whitehorse and then pretty much everywhere but cities over 1,000,000 people. Meanwhile, there USA has a meteorological office in like every city of even the smallest of sizes; it's just too political down there to shut them down when it's probably better to have fewer offices than they have but a lot more than we have.

This is currently the 7th wettest November since in the 1940s. At least at the station I just looked up.

Double the November average.

I miss just being able to blame Harper for everything. Made life a lot simpler. :lol:

Currently sitting @ 301.2mm for the month here in upper Mission, tomorrow I'll post my final total for November as we slide into December.

Wow, Fort St. John got hammered with snow (and a little rain) this month! Abbotsford and Vernon dry as a desert cactus by comparison!

Oh, and it's interesting that Vancouver was drier than normal with a record number of precipitation days...

EDIT: WHAAAT!? Hope is a lot drier than Abbotsford!? You're kidding me!

Wow! Hope and Vancouver tied for the same amount of precip for the month. Was that due to some systems moving south along the coast and not as much precip moved inland. I recall that happening a few times earlier in the month.

I ended with 257.2 mm -- slightly above average.

Interesting that we tied the record for days with rain despite the amounts not being very impressive.
