January Rainfall Stats
By Paul Homewood
The Met Office have issued the stats for January, so let’s see what they say for rainfall.
As the map shows, it has been much wetter than normal in the south. Over the whole of the UK,it has been the third wettest January on record since 1910, with 1928 remaining the wettest.
Taking all months, however, the 183mm recorded this month only ranks as the 18th wettest.
Whilst Southern England has been much wetter than the 1981-2010 average, the absolute rainfall map
Apart from a few isolated spots, the heaviest rainfall in the south has been 200m and 300mm. This level of rainfall is in fact not uncommon in other parts of England, not that this is any consolation for those suffering in the floods.
The implication then is that the rainbelts have shifted further south than usual. The Met Office have not yet issued their report, so it will be interesting to see if they comment on this aspect.
What is most significant, though, is the cumulative rainfall throughout the winter. I believe it is fair to say that most of the flooding we have seen in recent weeks has been the result of a steady build up of rain over several weeks, with the result that the ground is saturated and rivers full.
We therefore need to look further back before January to see what has been happening.
I’ll be posting on this tomorrow.
