These are just the stations deemed ‘Normals” by Environment Canada. The temperature is the departure from the 1971-2000 average in Celsius. I’m using monthly summary.

Woodstock Ontario – Coldest July Tmax in 142 Years

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

Using Environment Canada monthly summaries, Woodstock Ontario had the coldest average Tmax for July since 1872 (which is when the data starts).

Warm July’s seem kind of cyclic too on this graph.

This graph is just July’s monthly anomaly from the 1981-2010 average.

Toronto Airport A Little Cool This Year – Zero Days Over 30C So Far

Wow

““If Toronto’s Pearson International Airport weather station doesn’t hit 30.0ºC before the end of August — and it’s not looking like it will — this will be the first consecutive July and August that Pearson has not hit 30.0ºC+ since records began at Pearson in 1938 — that’s 76 years of data,” says Weather Network meteorologist Dayna Vettese.”

Here is a histogram collection showing that there have been 1371 days over 30C at the airport. But 2014 could be blank.

Note that “global warming” hasn’t caused any increase in “heat waves”.

More Sunshine in North America From 1982 – 2012

Filed under: Canada,Environment Canada Data,Sunshine,USA — sunshinehours1 @ 9:32 AM
Tags: , ,

Well … technically they say 4.2% less clouds. But that does mean more sunshine (except at night).

The emergence of satellite-based cloud records of climate-length and quality hold tremendous potential for climate model development, climate monitoring, and studies on global water cycling and its subsequent energetics. This article examines the more than thirty-year PATMOS-x AVHRR cloudiness record over North America and assesses its suitability as a climate-quality data record. A loss of ~4.2% total cloudiness is observed between 1982 and 2012 over a North American domain centered over the contiguous United States.

http://journals.ametsoc.org/doi/abs/10.1175/JCLI-D-14-00068.1?af=R&

 

As you know, land base sunshine monitoring is atrocious in North America. Once upon a time Canada had over 300 stations collecting sunshine data. How do we know whether major ups and downs in climate aren’t because of more or less clouds?

May 2014 – Canada is Cooling at -0.32C Per Decade Since 1998

Filed under: Canada,Environment Canada Data — sunshinehours1 @ 5:13 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.

Correction: I left the green line out of these graphs –   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 -0.32C/decade. Saskatchewan and Manitoba are cooling at over -.8 C /decade.  Wow.

Here are the trends for each province.

VANCOUVER HARBOUR CS May 25 (1958 – 2014)

Filed under: Environment Canada Data — sunshinehours1 @ 2:07 PM
Tags: , ,

I thought it was a little cold on Sunday (May 25) so I thought I would take a look at the daily data for a weather station near me using Environment Canada’s web service.

I picked  VANCOUVER HARBOUR CS which is in the harbour in Vancouver BC.

It turns out May 25 was the 6th coldest maximum temperature since 1958 (the start of the data) and the coldest since 1998.  It was also the 9th warmest minimum.

Remember, this is just one day’s data for 56 years. But there isn’t much of a CO2 signal is there? (Click graph for larger)

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.

There are 3 maps: TMean,TMin and TMax. Click on each for bigger.

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.
