Alberta Canada Tmax , Tmin and Tmean from 1873 (On 1×1 Grid) – It Was 2C Warmer in the 1940s

Published on by sunshinehours12 Comments

This is the Alberta followup the BC post. You can read the explnations.

In the terms of Tmax the coldest period in Alberta (using 5 year means) was 1972-1976.

The warmest period was 1940 – 1944. In fact it was 2C warmer in 1940-1944 than 2011 – 2015. (The 1930s were just slightly cooler than the early 40s)

You may ask why the green line of grid counts goes up and down so much. It appears there are many more stations reporting in May/Jun/Jul/Aug/Sep than in the winter.

British Columbia Canada Tmax , Tmin and Tmean from 1873 (On 1×1 Grid)

Published on by sunshinehours15 Comments

Step 1: Use Data from Environment Canada’s monthly summaries.

Step 2: Summarize the data by 1×1 grid square so no region dominates.

Step 3: Graph Tmax, Tmin and Tmean.

The black line is the monthly data. The blue boxes contain the 5 year mean (and I set the 5 year period by just going back from the most recent data in 5 year increments)

The green line is the number of 1×1 grid squares. The blue dashed line is the trend from 1873 (which is the earliest data).

(I won’t count the pre-1900 data as too important since there were so few stations)

Tmax was 1.5C  warmer in the the 1920s/30s/40s than now.

Tmin now is the hottest its been since 1900.

Tmean in the early 40s was slightly warmer than now.

Tmean/Tmin has been warming since 1970 thanks to Tmin … not Tmax.

Nanaimo Tmax from 1947 to 2015

Published on by sunshinehours16 Comments

Every once in a while I visit the data for the weather station closest to my hometown on the west coast of Canada.

Today I am looking at daily TMAX data  from Nanaimo Airport (1947 – 2015).

1987 was the warmest year (1958 was 2nd warmest FYI) . 1955 was the coldest They are shown as the orange and blue lines.

Here I have graphed all the available data in the style I usually use for Sea Ice data.

2015 is in red. There are gaps because Environment Canada doesn’t seem to care.

Notice that temps can fluctuate by 20C for the same day in different years.

Ponder this … why can we humans (and crops and animals)  adapt to 20C swings but we can’t adapt to a 1C change over 100 years?

Nanaimo Tmax from 1913 to 2014 Using Two Overlapping Stations

Published on by sunshinehours12 Comments

Every once in a while I visit the data for the weather station closest to my hometown on the west coast of Canada.

Today I am looking at daily data (using KNMI) from Departure Bay (1913 – 1992) and Nanaimo Airport (1947 – 2014).

I’ve summarized the data by monthly mean.

The data does overlap. The first graph is just Tmax. The second graph is Tmax anomaly from the overlap period of 1948 to 1992

Nanaimo Tmin and Tmax from 1980/1998/2010

Published on by sunshinehours16 Comments

Update: From 1948 added at bottom

Every once in a while I visit the data for the weather station closest to my hometown on the west coast of Canada. The data only starts in the late 1940s so there is no extreme’s from the 1930s and 1940s.

The three graphs below have the Tmin and Tmax data from the Environment Canada monthly reports up to the end of 2014.

The three start in 2010, 1998 and 1980. What does the data tell you?

If you start in 2010 … we are going to bake to death.

If you start in 1998 … we are slowly cooling.

If you start in 1980 the Tmin is climbing and the Tmax is dropping. UHI probably.

November 2014 – 30% of Canadian Stations Were in the Coldest 5 Tmin

Published on by sunshinehours14 Comments

Using November Tmin data from Environment Canada’s monthly summaries.

I used the following filter. There had to be 25 years of data. And there had to be data in 2014.

420 stations fit that criteria.

For 122 of those stations, November 2014 was in the top 5 coldest.

So, for example. 108 MILE HOUSE ABEL LAKE has 27 rows of data, and 2014 is ranked as the 4th coldest.
