| 14th October 2011: A fine October day | |||||||||||||
| High
pressure was centred to the east bringing a light south-easterly
from the Continent. As the day dawned, the clouds were hardly moving
but gradually the wind picked up from the south-east, and then
turned north-easterly during the day. For a while, a sea breeze
brought a rolling cloud bank in, but this was disrupted as the wind
changed direction and the sun broke through. Extremes and totals for 14th Oct 2011

front passes over at 19:20, the sky clears and the wind abruptly
changes direction to the NW, the temperature also drops several
degrees. Extremes and totals for 4th Sep 2011

| 27th March 2011: A fine, if rather hazy spring day day in one minute | |||||||||||||
|
The day was a hazy one as the air mass was of Continental origin and there was little if any wind to 'blow' away the thick haze that caused the horizon to disappear into a white murk.

| 20th March 2011: A fine spring day day in one minute | |||||||||||||
|
The day dawned with patchy cloud but by mid-morning the cloud had melted away and the sun shone all afternoon. A maximum of 15.5°C with light winds made it feel quite warm in the sunshine. Note the wind shear just after dawn where the higher clouds (associated with a decaying warm front) are moving in from the west, but much lower level clouds are coming up from the south and rolling as they do due to the effects of shear. The movie is composed of 2500 separate images taken 30 seconds apart and then played at a speed of 20 images a second. |
