13th
April 2012: A chaotic cirrus sky and a sun halo too
With high
pressure centred to the north west, there was a slack northerly flow
over the whole of the British Isles bringing a showery regime. Here
in the Otter Valley, heavy, thundery showers developed just a few
kilometres inland but here near the coast a sea breeze meant it was
dry and mostly sunny, though that sunshine was rather hazy at times. Extremes and

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

September 2011: A fine late summer's afternoon then a cold front
approaches
Low
pressure was approaching the north of the British Isles with a cold
front. The video starts with fair weather cloud (cumulus) but then
cloud increases as the cold front arrives with rain. Note how the
cloud speed accelerates and the wind direction is from the SW. The
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

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.

movie is composed of 2500 separate images taken 30 seconds apart and
then played at a speed of 20 images a second.
