Nanaimo Hot and Cold Day Histograms – So Much For Extreme Weather

Filed under: AGW is a Cult,Extreme Weather,Mockery — sunshinehours1 @ 12:17 PM
Tags: , , , , ,

You all know that the AGW cult likes to go on and on about “Extreme Weather” because the warming stopped in 1998 and they like to think the world is coming to an end and only they can save us. Just another end of the world cult.

So I thought I would look at the same 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.

One thing to remember. The 2361 Days Over 25C number (for example) includes the 506 Days Over 30C etc.

I don’t see any increase in extreme hot days. I don’t see any increase in extreme cold days.

Aside from 2 hot days in July 2009 (matched by the 3 days in the 1960s) and 1 cold day in 2008 matched by a day in 1968 it seems to have been getting less extreme.

More Sunshine in North America From 1982 – 2012

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

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.

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

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.

Canada February 2014 – Monthly Mean Temperature Anomalies Mapped

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.
