The relationship between volcanoes and Central England Temperature in recent years

Now that I’ve discovered the VEI database from the NCEI, I can now overlay volcanic eruption events on top of the monthly CET anomalies and chart the results. In the above chart (fig 2) I’ve overlaid all the VEI 4 events or greater from 1980, and was surprised to find that there seemed little in the way of correlation between them. The Pinatubo eruption of the 15th of June 1991 for example was the first VEI 6 event since Tambora in 1815 (fig 1), and lifted more than 5 cubic kilometres of material 25 miles straight up into the stratosphere, coincidentally a typhoon that was passing close by to the Philippines at the same time scattered the ash from the volcano to the four winds. I thought the effects of this would have had a dramatic cooling effect on CET in 1992, but not that you would notice. Of course any cooling in a local temperature series may well be masked by other regional and global factors that influence CET that are going on at the same time, global climate is complicated.

About xmetman

I am an exmetman who is passionate about all things to do with weather and climate. I have no axe to grind, and am continually upsetting people on both sides of the global warming debate with the articles that I publish, hell, I'm even banned from commenting on the Met Office's own blog! What I do fight for is the freeing up of climate, observational and forecast data collected and created on our behalf by the Meteorological Office.
