Weather and climate round-up

First taste of winter next week:
听
After a mild autumn so far, the UK is about to experience its first taste of winter next week.
听
Cold air is expected to flood southwards across the UK from Tuesday.
听
As it meets the relatively warm sea vigorous convection is expected, with the risk of heavy showers - even thunderstorms in some coastal areas.
听
For our region, showers that develop are likely to fall as snow down to quite low levels at times, with accumulations in places 鈥� especially over the North York moors and Wolds.
听
There will though be big variations with some inland areas seeing a lot of dry and sunny weather, but with frost at night.
听
All in all, this early taste of winter is pretty normal for late November and by no means exceptional.

Possible reason for 鈥榮lowdown鈥� in global warming
听
Research out this week points the finger at reduced levels of CFC gases in the atmosphere following a ban on their use in the 1980s as a possible reason for the levelling off of global temperatures in the last 15 years or so.
听
CFCs, widely used in fridges and freezers until they were banned in 1987, are 10,000 times more powerful a greenhouse gas than carbon dioxide.
