April couldn’t have been more different to February for Western Europe with frequent Atlantic lows (active rossby wave train) bringing record rainfall to the UK. This ‘stuck’ pattern was abruptly replaced by only another stuck pattern, a blocked high (stationary wave) which brought 4 straight weeks without a drop of rain for some. The tap […]
If you’ve read my latest articles and watched the videos then you’ll be well aware that our warm, wet winter was largely down to the warm ‘enhanced’ phases of the madden julian oscillation. The northward heat release fueled a highly active wintertime rossby wave train. At the end of March, the MJO finally weakened into […]
A persistent high pressure system anchored between Scotland and Scandinavia has led to a complete shutdown of ‘weather’ and produced significant April rainfall deficits from UK through Central Europe as a result. This blocking high has re-routed all weather north into Scandinavia and south into Iberia. 500mb height anomaly for April so far. Rainfall anomaly […]
What’s going on? We have gone from relentless rain to unusually dry in just 6-8 weeks. From almost UK-wide flood warnings in February/early March to little or no rain from March 19 to April 16. This was the 500mb height anomaly for February. This was the result. A record wet February for the UK. As […]
While Easter 2020 will be far from anything anybody’s witnessed before, the weather will actually be not too dissimilar to last year which turned out record warm throughout the UK. https://twitter.com/MarkVogan/status/1251907422438019074 Like last Easter, we have a nice warm, near summer-like high centred east of the UK off the Danish, Dutch coast, as this system […]
The global driving mechanisms of ENSO, IOD and MJO which drove the hemisphere’s warmest winter and UK’s wettest February on record have finally changed gear but much too late for the snow and cold lover unfortunately. As a result of this ‘gear change’ combined with the natural seasonal shift, the westerlies have slackened and ridging […]
A strong, stable stratospheric polar vortex dominated much of the 2019-20 boreal winter, driving warm oceanic air across the continents. We’ve almost certainly observed the warmest winter since the beginning of the satellite era (1979) throughout the Northern Hemisphere. Globally, January 2020 was earth’s warmest since the beginning of the satellite era in 1979. Following […]
Winter 2019-20 could not be any different to the winter of a decade ago. In fact it’s the polar opposite to 2009-10 which was one of the coldest. 2019-20 will go down as one of the warmest for the entire hemisphere never mind North America or Europe. Cities such as Oslo and Helsinki received their […]
Thanks to the collision of arctic and tropical air over North America and the North Atlantic, the jet stream crossing the pond has intensified to supersonic speed, creating the perfect incubator for rapid cyclogenesis and formation of the Atlantic’s deepest depressions in several years. A visible satellite image captured this morning shows a storm system […]
Whether we blame the burning of fossil fuels, sun, oceans or nature cyclical variability, if we trust the graphs and data shown to us, then there’s no denying that our global temperature continues to rise. Recent years certainly ‘appear’ to be producing more heat than cold globally. There appears to be less global cooling following […]
