Snow Graphs From the Rutgers Snow Lab

 

These graphs are NH only.

Its a pity Rutgers graphing script can’t spell Hemisphere.

But …

Fall up 1,500,000 sq km

Winter up 900,000 sq km

Spring down 3,000,000

NASA Predicts: ‘there are no guarantees’

I was quite sure NASA knew exactly what was going to happen. Don’t they model the climate? Don’t they use those models to ask for big grants. Now they are saying that literally anything could happen. Then what use are they?

‘If past events help predict future ones, then we have probably reached the peak of the 2015–2016 El Niño,’ the space agency said.

‘Warmer-than-average waters in the eastern tropical Pacific Ocean should start to cool off and shift westward.

‘By summer, the tropical Pacific might be back in a neutral state or La Niña cooling could kick in, as it did after major El Niños of the past.

But will the ocean respond in 2016 the way it did in 1998 and 1983? Given that the planet is hotter than at any time in the past 135 years, there are no guarantees.’

British Columbia Canada Tmax – Missing Data April 2015

This a followup to this post: British Columbia Canada Tmax , Tmin and Tmean from 1873 (On 1×1 Grid)

The following map shows which stations were missing (or not missing) daily Tmax data in the monthly summary for April 2015.

Blue had 0-3 days missing. Red more than 3. What saddens me is that 19 out of the 43 “red” stations were also “Normals” – which means they were reference stations.

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

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.
