Cool Rio

Before the temperature data stopped flowing out of Weather Underground, I thought my Stations had settled into a Top Ten that wouldn’t change. But in Week 33, after normal service resumed, there were some rather extreme figures which returned Koltsovo to Number 1, Buenos Aires moved up to 6th (after propping up the table for the first five weeks of the meteorological year), and Mumbai pushed Rome into tenth place. The bottom two swapped places the following week and the top two the week after. The latest Table looks like this –

You will notice immediately that all ten stations now have a running average Mean Daily Temperature below the feared 2°C.

Positions may change again but I’m going to do Sunday posts for the rest of the year that will feature just one of the ten stations, starting with the “warmest”, then the “coldest” in the northern hemisphere, and so on.

After the heatwaves, things have cooled noticeably. The Ten returned a temperature of only 0.26°C above Pre-Industrial last week. (My weeks, by the way, run from Saturday to Friday.)

36_FullTable

You will see from this full Table, with added DurhamTees data, that my nearest reliable local station broke through the two-degree barrier – but for the year-to-date is nonetheless running 0.47°C cooler than the “Ten Station Globe”.

Here is the first of the 10-week cycle set of graphs.

The ten-week histogram shows Rio’s almost 3.5°C range in average Mean Temperature above Pre-Industrial, and there’s no need for an added trendline to indicate the cooling. The small Rio graph for last week does, however, indicate how much it warmed from the Sunday low point. It didn’t feel particularly warm on the Yorkshire Coast last week but the figures suggest otherwise.

Welsh Peak

A day or two ago Scotland posted a record February high temperature. Today, Trawsgoed in Ceredigion reported 20.6°C (source: BBC), the first time a temperature over 20°C has been recorded in a UK winter.

On the last day of winter in 2012, Whitby maxed at 18.1°C. At my chosen weather station in the town, the warmest days of February for the past nine years have averaged 12.5°C, with the lowest maximum being 7.8°C, in 2010.

Wales isn’t the globe, but Where’s Eddy?”
