The data is from the daily data put out by Environment Canada. (It is wrong sometimes)

These are ONLY the “Normals” stations (the stations EC calculates anomalies for from the 1971-2000 mean)

The black circle in the top left corner represents 5C divergence from the “Normals”. Blue is cold. Red is warm. Click for bigger. Refresh to make it start over.

Canadian Weather Stations 1841 to 2014 – The Movie

Filed under: Canada,Environment Canada Data — sunshinehours1 @ 3:56 PM
Tags: ,

Using the Environment Canada monthly summaries  I have made up 2 gif movies that show which weather stations reported data for each year from 1841.

1974 with 2826 is tops for number of stations. In comparison, 2014 so far only has 1215 stations. There were more stations reporting in 1951 than 2014.

(I don’t know why a weather station in South Dakota shows up in the monthly summaries.)

The 1841 to 1864 part is kind of slow. Toronto is the only station. One gif has Station Names. Not terribly readable. But fun. Click for bigger.

Canada February 2014 – Monthly Mean Temperature Anomalies Mapped

Filed under: Canada,Environment Canada Data — sunshinehours1 @ 10:43 AM
Tags: , , , , ,

I have mapped the February 2014 mean temperature anomalies in the Environment Canada monthly summaries that have “normals”. The anomalies are calculated from selected stations based on the 1971-2000 average.

The size if the dot represents the size of the anomaly. The 5C black dot in the top left hand corner represents 5C difference from “normal”. Red dots are warmer than normal. Blue are cooler. And Green are 0.

Most of the prairies averaged 5C or more below “normal”. Click for bigger.

British Columbia February 2014 – Coldest and Warmest

Using data from Environment Canada, these are the 25 coldest/warmest days in BC weather stations.

Something new I learned was that PUNTZI MOUNTAIN was a Pinetree Line base. While I was never anywhere near Puntzi Mountain, a long, long time ago I did spend 2 nights at the Kamloops Pinetree Line base. The “new” computer room was pretty big. The “old” computer room was massive.

Snowfall in Canada January 1966 – Possibly the Snowiest Month Ever in Canada

Filed under: Canada,Environment Canada Data,Snowfall — sunshinehours1 @ 3:44 PM
Tags: , ,

Yesterday I did a post looking at Snowfall in Canada for January 2014. After that I wondered what was the snowiest month in Canadian history?

I chose two semi-arbitrary criteria. Lots of weather stations so after 1940. And the largest average snowfall for all stations combined.

January 1966 was at the top of that list. Map of snowfall in Canada for January 1966 from Environment Canada’s monthly summaries.

The size of the black dot in the top left corner represents 100cm of snow. KITIMAT TOWNSITE got 436.9cm in January 1966. For the non-metric, that is 172 inches.

The Sad State of Environment Canada’s Sunshine Data

Filed under: Canada,Environment Canada Data,Sunshine — sunshinehours1 @ 12:06 PM
Tags: , , ,

Once up a time (June of 1978 to be precise)  if you downloaded Environment Canada’s monthly summaries, you would have found 313 stations with “Bright Sunshine” hours.

As of January 2014, there is only one. (Ignore the title. Those are hours , not anomalies. I’m just depressed about the loss of data. How do we know whats going on if we don’t collect sunshine data???)

Canada is Cooling at -0.13C Per Decade Since 1998

Filed under: Canada,Environment Canada Data — sunshinehours1 @ 9:07 AM
Tags: ,

Environment Canada publishes monthly summaries here. The data included Tmax, Tmean, Tmin and Normals (the D column). The Normals column is “Mean Temperature difference from Normal (1971-2000) (°C)”. These are supposedly the higher quality stations. Only some of the stations get a Normals value.

I could just look at the stations with Normals and summarize the data. But some of the stations are close together. So I thought why not summarize the data by 1×1 grid square and then summarize the grid squares. The green line is the count of grid squares with data in them. That is dropping like a stone. (I will discuss this in another post).

And why not see what happens from 1998. We know 1998 is a pivot point in climate.

The trend for the whole country from 1998 is cooling at -0.13C/decade. The big surprise is Ontario. The last time I did this it was warming. Here are the trends for each province.

All  -0.13
BC   -0.20 
ALTA -0.35 
SASK -0.53 
MAN  -0.56

Canada January 2014 – Monthly Anomalies Mapped

Filed under: Canada,Environment Canada Data — sunshinehours1 @ 5:54 PM
Tags: , , ,

I have mapped the January 2014 anomalies in the Environment Canada monthly summaries that have “normals”. The anomalies are calculated from selected stations based on the 1971-2000 average.

The size if the dot represents the size of the anomaly. The 5C black dot in the top left hand corner represents 5C difference from “normal”. Red dots are warmer than normal. Blue are cooler. And Green are 0.

Not much sign of the Polar Vortex in BC and Alberta for January. A big change from December.
