Winter Rainfall UK 1910 to Jan 2014

Filed under: AGW is a Cult,Drought,Precipitation,UK Met — sunshinehours1 @ 11:21 PM

Because of the floods, they are arguing about the amount of rainfall due to “climate change” over in the UK. Looking at the data from the UK Met for winter rainfall, it appears rainfall goes up and down.

I wonder if the usual AGW alarmist media blamed climate change for the dry period 2009 to 2011? Do I have to ask? Of course they did!

Guardian 17 November 2011: As well as the recent dry weather, water companies and environment regulators are expecting the UK to have more frequent dry winters as a result of climate change.

UK May Tmax temperatures cooling at -.618C / decade for 15 years

Using data from the UK Met, May Tmax (mean maximum temperature) in the UK is cooling at -.618C / decade for 15 years.

The warmest May Tmax (in the last 104 years) was 16.9C in 1992. May 2013 was 13.8C. Tied for 33rd coldest out of 104.

CO2 seems to not work in May in the UK ….

UK Decembers Tmax Cooling -.45C/decade for 30 years and Sunshine is Up Too

Filed under: Sunshine,UK Met — sunshinehours1 @ 1:19 PM

Using UK Met data from here, I noticed that Tmax for Decembers are cooling at -.45C / decade for 30 years.  Thats a lot!

And then I wondered why? A theme I have returned to over and over is that hours of bright sunshine has increased because of cleaner air. Could more sunshine in December lead to cooler Decembers since clear skies can lead to colder temperatures in winter?

Guess what. Sunshine is up an average of 5.5 hours per year in December for the last 30 years. And compared to 1988 sunshine is up 80% in December. Instead of 28 hours of sunshine in December, the average is closer to 48.

UK Tmax versus Sunshine are well correlated. Cleaner Air. More Sunshine.

This graph is Tmax % of normal versus Sunshine% of normal. The curved lines are the Loess curves from [R]. Data retrieved from here.

Why would sunshine be higher? Cleaner air in the UK (until China and India started to burn a lot more coal) thanks to the Clean Air Acts of 1956 and 1968.

The loess curves bottom out around 1968/1972.

UK Met Bright Sunshine 5 year averages plotted using all monthly anomalies

An addition to this post on 5 year averages using NOAA data. This time I am using UK Met Bright Sunshine data.

1) The current 5 year period has less bright sunshine than the previous 5 year period.

2) The previous 5 year period had no large negative anomalies, and no unusual positive anomalies, yet it was the most sunshine since 1929.

3) The period from 1988 to 2008 was the longest without a -50 hour anomaly.

4) The large negative anomalies are returning to normal.
