CDL 19: That Was August

The Met Office revised its seasonal forecast for the UK’s summer weather in June, July and August 2009, following a period of wet weather across the country.

Earlier this year, the organisation had declared that there was a 65% probability that the summer would be warmer and drier than average, and that it was “odds on for a barbecue summer”. Residents and tourists were advised to seek ways to stay cool, to find shade during the hottest times of the day, and to stay hydrated.

However, following a long period of wet and windy weather across the UK recently, it has adjusted its forecast. According to the Met Office, August will have near or above average rainfall – around 84.6mm – while temperatures will probably be near or above the average for the year, which is 14.7 degrees Celsius.

The Met office defended its earlier seasonal forecast. In a statement, it said: “We acknowledge that the weather we have seen through the last month has been disappointing, especially after the fine weather through June and the heatwave at the end of June and beginning of July.

“At no time did the Met Office state that summer 2009 would be hot and dry throughout, or forecast a ‘scorcher’.”


CDL 18: The Van Allen Belt

The Van Allen Belt

It is believed that protons of energies exceeding 50 MeV are the result of the beta decay of neutrons created by cosmic ray collisions with nuclei of the upper atmosphere. The source of lower energy protons is believed to be proton diffusion due to changes in the magnetic field during geomagnetic storms.



Next-generation DNA sequencing has the potential to dramatically accelerate biological and biomedical research, by enabling the comprehensive analysis of genomes, transcriptomes and interactomes to become inexpensive, routine and widespread, rather than requiring significant production-scale efforts.
