I was wondering if someone could give me a rough estimate of when it starts to improve each year?
The reason we have sh*te weather in the winter is because the Polar front moves south as the ITCZ (the thermal equator) moves south.
The north of the Polar front is dominated by lows and the south dominated by highs. The lows and highs get all mixed up at the polar front causing lots of little cold and warm fronts to form, these occlude to make the weather even worse! Incidently, the jet stream snakes it's way between the highs and lows.
Once the ITCZ moves north again (it lags behind the actual position of the Sun by a few weeks) the polar front will move north again to about 65N and keep the crappy weather where it belongs. This process should start to have a noticable effect sometime around April(ish). I would have throught that mid-March(ish) the weather will be less changeable at least.
