Tornadoes. A climate view of tornadoes. Possibly the hardest brief yet. There is very little that is certain about climate change and tornadoes. When and where a tornado outbreak in the US occurs is predominantly determined by weather patterns that bring together the warm moist air from the Gulf of Mexico and the cold dry air from the North. Because these weather patterns are very variable from year to year, it is hard to establish any long term effect of climate change.
The WMO have today released their State of Global Climate in 2016 report, detailing a record global temperature, exceptionally low sea ice, continued sea level rise and increasing ocean temperatures, with extreme weather and climate continuing into 2017.
The authoritative annual statement is based on several international datasets maintained independently by global climate analysis centres, as well as research institutes and national meteorological and hydrological centres.
Now it’s December, one of the questions we are often asked as meteorologists is “Will it be a white Christmas?” The first thing to clarify, is what exactly is being asked – do you want to know if anywhere in the UK will see a single snow flake or are you envisaging streets and roofs with a dusting of the white stuff when you wake up on 25 December.
The latest weather satellite has been successfully launched into orbit by NASA on Saturday. It features six new sensors, much greater processing power and will capture more hi-res imagery, improving weather observation capabilities, leading to more accurate forecasts and warnings.
