According to this article I’ve read in the Guardian, changing the flight path of aircraft could reduce their effect on climate change.
These are the temperature anomalies for 12 UTC today showing what a particular wet and unpleasant day it’s been down here, with negative anomaly values of -2 and -3°C. Having said that the rain is continuing to move away southwestwards, and there are now some chinks of blue sky appearing on the northeast horizon, as the cloud starts to thin and things start to dry out a little here in mid Devon. Further north, and away from the east coast, there are positive anomalies of +2 or +3°C, on what’s been a lovely sunny spring like day.
According to the latest forecast charts (fig 3) it looks like we are in for a spell of cold easterly winds right through this coming weekend along the south coast and especially in the southwest. In fact it might not be till the middle of next week before that nagging easterly starts to veer round to the south. Today feels more like January than the middle of March in our part of Devon, and it reminds me of the old rhyme:
When the wind is in the east,
‘Tis neither good for man nor beast;
When the wind is in the north,
The skillful fisher goes not forth;
When the wind is in the south,
It blows the bait in the fishes’ mouth;
When the wind is in the west,
Then ’tis at the very best.
Hopefully the frontal cloud that’s spinning around the low might start to thin and break by Saturday and at least then we might get some sun, although the easterly will still be blowing. Further north things look more quiet under the influence of an anticyclone that’s firmly anchored over northern England, so there it will be more a case of sharp overnight frosts, followed by sunny days.
This chart is of 365 day centred rolling daily mean CET temperature anomalies for the last 30 years. Just to complicate things, I’ve overlaid a 14 day moving average on top of this just to smooth things out a bit. The LTA that I have used to calculate the anomalies is the latest possible 30 year period that I could use i.e. 1987-2016. The decadal linear trend for the last 30 years is just +0.08°C per decade. Of course, things would look different if I had used a longer period or an earlier LTA, but such is the way with statistics.
These are some plotted climate charts for yesterday across the British Isles and near continent. They include sunshine for yesterday, precipitation [06-06 UTC] and maximum [06-18] and minimum temperatures [18-06]. It’s not particularly exciting I know, but I was just looking at another way of displaying the charts that I generate from how I have done it in the past.
The only time that you see the ground white in Devon these days is if there’s been a touch of frost or a hail shower, so the shower that we’ve just had was a bit of a treat. Large CB’s towards the east and approaching from the west at the moment, bringing April showers a little early this year.
