The short-lived hot period in the south and east is being replaced by a westerly airflow for the UK, bringing showers and some longer spells of rain for some in the coming days and a return to nearer-average temperatures for the time of year. Which day(s) will be dry this week? Find out

. During the 1960's with the advent of computers the Met Office was at the forefront in developing the first simple dispersion computer models. However, it was the Chernobyl incident in 1986 that triggered the start of the development around the world of sophisticated atmospheric dispersion models

The slowdown in the rise of average global temperature had been observed in the recent temperature record, but with the last three record years, this slowdown has ceased. Prof Stephen Belcher said: “After a period during the early 2000’s when the rise in global mean temperature slowed, the values
