When checking up on the link for a post elsewhere on this forum http://www.ww2talk.com/forum/1940/32785-weather-services-war.html, I realised I should post this: History Royal Meteorological Society, UK, Weather and Climate, also from the Royal Meteorological Society, UK, Weather and Climate website. At this page it is possible to download reports on The Met Office, Dunstable, and the IDA Unit in World War II, Meteorological services leading to D-Day and The Met Office Grows Up: In War and Peace.
METEOROLOGICAL SERVICES LEADING TO D-DAY by R.J. Ogden https://www.rmets.org/sites/default/files/hist03.pdf
https://www.rmets.org/sites/default/files/hist07.pdf Excerpt from above link. "When war broke out, only former members of the Meteorological Reserve were available for mobilisation – seven officers and 22 other ranks to fill an establishment of 30 officers and 124 other ranks. Transportation, equipment and communications were also matters that needed to be sorted out. Nonetheless, two sections of RAF meteorologists were soon attached to Numbers 1 and 2 Survey Regiments, supporting the Army in France and Belgium, and these became directly involved in front line conflict. Their story has been largely neglected".
