Rest of Europe
We have bookend lows in extreme SW and NE of the continent while high pressure dominates in between. The jet is splitting west of Ireland with the greatest energy on the southern branch, hence why we have a major low bringing wet and stormy conditions to the Canaries, Northwest Africa extending into southern Iberia. Impressive shelf cloud rolling in […]
We continue our journey from summer into winter and it’s often a rollercoaster ride. This week shall be no exception. On the other side of the Atlantic, a storm system has swept away record 80-degree weather day after day over the Northeast US and replaced it with cold, windy and even snowy conditions. This dramatic contrast has accelerated the trans […]
In the wake of a record warm September, a strongly negative Arctic Oscillation (AO) with persistent blocking high pressure over Scandinavia which has made for a cold October. -AO forced by a nice tropospheric warming event. October temperature anomaly so far this October. It’s been a record warm October over the Eastern United States. Note below the […]
As we enter the final 10 days of October I continue to gather the remaining evidence in order to put forward my 2016-17 winter forecast. The latest information regarding Arctic Sea Ice states that for the time of year, we have the lowest levels on record as you can see from the below chart. Look […]
As your well aware, we’ve a very blocked up pattern with high pressure repositioning back into Scandinavia while Atlantic lows get diverted into Iberia and south-central Europe. However, the driving mechanism to our weather can be traced back to North America. In today’s written post I want to show you the GFS jet stream chart through the […]
At this time last year, the polar vortex was strong and continuing to strengthen, likely influenced by the heat discharge emitted by the oncoming Super El Nino with a firm low over high pressure hemispheric 500mb pattern. This laid to dominant zonal, oceanic influence on both North America, Europe and indeed Asia. This year it’s been weak and this along with a […]
As forecast, the Scottish Highlands have received their first widespread covering above 3,000ft thanks to the passage of a cold front overnight which brought heavy and persistent rain for a time. Winds veered northwesterly and this drove in our first real push of ocean modified Greenland air. This morning is more like late October. This morning’s view from […]
Before we focus on the Western Europe short range I want to pan out and look at the bigger picture because it’s this that explains the finer details. Firstly, Nicole remains a hurricane and a hurricane that’s getting unusually far north. As you can see from the below NHC track forecast this system is expected […]
Arctic Oscillation and Polar Vortex Analysis and Forecasts October 13, 2016 Special blog on winter retrospective can be found here – http://www.aer.com/winter2016 Dr. Judah Cohen from Atmospheric and Environmental Research (AER) recently embarked on an experimental process of regular research, review, and analysis of the Arctic Oscillation (AO). This analysis is intended to provide researchers and practitioners real-time insights on one of […]
This morning 29 years ago, much of southern Britain woke to a scene of damage and destruction. This storm is particularly close to my heart as I lived through this once-in-a-lifetime event in central London aged 4 and believe this sparked today’s obsession with all things weather! The Great Storm of 1987 MET OFFICE A […]
