I’ve been producing scatter correlation graphs for UKUK The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in Europe, off the north-western coast of the continental mainland. It comprises England, Scotland, Wales and Northern Ireland. gridded data for a number of years now, but recently I tried the same idea with climate data drawn from SYNOPSYNOP SYNOP (surface synoptic observations) is a numerical code (called FM-12 by WMO) used for reporting weather observations made by manned and automated weather stations. SYNOP reports are typically mad hourly and consist of groups of numbers (and slashes where data is not available) describing general weather information, such as the temperature, barometric pressure and visibility at a weather station. data for many stations for a single time period. I’ve now developed a viewer that displays a scatter chart of monthly rainfall POAPOA Percentage Of Average along the X axis, with temperature anomalies along the Y axis. To differentiate between each country I’ve coloured coded each point with one of five different colours. As you can see for April 2023 it works quite well, and you can quickly see that Scotland (blue) had a cold but reasonable dry month, whereas England (yellow) were much wetter.
The above scatter graph shows the correlation between rainfall POA (Y axis) and sunshine POA (X axis), and again it’s easy to see at a glance how much more sunnier and drier Scotland were when compared to England. I’m sure it will be only a matter of time before someone else uses this idea of mine.
