Weather and Climate
|Group Contact||Len Wood|
|Venue||Knighton Room, next to Wembury Village Hall|
|Day/Time||1st Thursday of the month from 2 pm - 4 pm|
IMPORTANT NOTICE - Due to the coronavirus situation the group is not meeting for the foreseeable future, however I am communicating various topics to the group via email and asking for questions which I will try and elaborate on for the whole group.
We are having a lively exchange of cloud photos.
This will be ongoing and as frequent as I think necessary.
I had thought I might use Zoom but think that using email will be more inclusive for those who are not so IT savvy.
We had a mild autumn (September to October) in Wembury with the mean temperature being 0.3 °C above the 30-year average. There has been discussion as to whether Decembers are getting wetter. Records since 1985 in Wembury show this to be true. Rainfall for the last four has been above average. So far to the 27th we have had 201 mm, almost twice the 30-year average for the whole month of December which is 118 mm.
During the cold spell at the beginning of December, Jayne Richardson took this photo on one of her early morning walks in Wembury. Look closely over the sea just offshore and you can see the sea 'steaming'. This is called 'Arctic sea smoke'. Or maybe 'Wembury sea smoke'. Cold air over relatively warm sea can cause this apparent 'steaming'. There usually needs to be a temperature difference of 10°C or more. This is common in the Arctic. The sea temperature off Wembury was about 12°C and the air would have been around 1°C. (Julie will put this picture on the website very soon! sorry)
Have you ever wondered why it rained so heavily, or why the weather forecast was wrong? If so, this might be the Group for you.
Each session will be topic based, but will include a discussion of the current weather and the previous month's weather.
If any extraordinary weather has occurred, in the context of our usual climate, it will be discussed.
