Climate change, with more and more storms and heat waves, also has consequences for our energy supply. An international research team has now developed a new method for calculating how extreme weather affects energy systems.

Rapid Arctic warming has not led to a 'wavier' jet stream around the mid-latitudes in recent decades, pioneering new research has shown.

One of the ocean's loudest creatures is smaller than you'd expect -- and will get even louder and more troublesome to humans and sea life as the ocean warms, according to new research.

The extra-tropical storm Dennis was a remarkable system. This extremely deep low-pressure system over the North Atlantic bottomed at near 920hPa on Saturday evening, located just south of Iceland. Dennis has become one of the most intense extratropical cyclones on record. Its behavior and stunning imagery rival the famous ‘Braer storm’ – the most intense […]

February is the last official meteorological winter month. That means that meteorological spring starts with March 1st. Of course, the weather does not simply change overnight, so there are gradual changes occurring as the weather seasons slowly shift. Here is the 850mb raw temperature forecast from the GEFS ensemble forecast system. You can nicely see […]

We are at the final stage of large cyclone #Dennis tonight through Monday. While it continues moving east into northern Europe, it is weakening and delivering severe winds into SW Scandinavia. Also, lots of rain and snow into SW Norway, increasing the avalanche threat. 18 UTC analysis today revealed Dennis’ center has the minimum central […]

Ahead of the large extra-tropical cyclone #Dennis over the North Atlantic and western Europe, and its associated surface cold front, a powerful warm advection is delivering an incredibly warm airmass into northern France, parts of Benelux and northwest Germany this evening. The event is related to the strengthening warmth wave over continental Europe this weekend. […]

The ‘bomb cyclone’ #Dennis took it seriously, no doubt about that. What we have seen today (Saturday, Feb 15th) is indeed beyond exceptional and photogenic for extra-tropical cyclones no matter where. The structure, its behavior and satellite presentation is simply EPIC! The system has deepened to remarkably low pressure for North Atlantic, 920 mbar this […]

Only a week ago, a new highest temperature record has been reached for the continent of Antarctica. It was measured at the Argentine station Esperanza, situated on the Antarctic peninsula. But now an even higher temperature has been measured on Seymour Island. The continent of Antarctica has experienced its warmest temperature on record, reaching 18.3°C […]

The bombogenesis / explosive cyclogenesis #Dennis is underway across the North Atlantic this morning, centered northwest of Ireland. The intensification rate is very extreme as the observed pressure falls are more than double the threshold for the bombogenesis! The pressure change during the past 24 hours has been unprecedented, as it has changed from 987 […]

While the main focus is on the volatile environment across the North Atlantic and western Europe these days, such pattern is usually responsible for upper-level ridging over Europe. Resulting in much above normal temperatures. This weekend, an extreme warmth develop over central Europe first, gradually spreading across eastern Europe and the Balkan peninsula until Tuesday. […]

A new intense North Atlantic windstorm #Dennis could potentially push its central pressure to near or even below 915 mbar tomorrow, challenging the all-time lowest pressure record. The record-holder is the Braer storm, which occurred on Jan 10/11th, 1993. Its lowest pressure bottomed at 913 mbar and remains the most intense extra-tropical cyclone ever recorded […]

The intense windstorm over Iceland has resulted in extremely severe winds in some areas, especially where downslope winds have contributed to violent gusts exceeding 200 km/h. The weather station Hafnarfjall reported an incredible wind gusts of 255.6 km/h (= 71 m/s = 159 mph) this morning, 11 GMT. The hourly average was 108 km/h (= […]

Latest satellite imagery and weather station data across Iceland indicate the extremely severe winds are fully developed across the North Atlantic. The mature stage of a very large extra-tropical cyclone has brought a strong pressure gradient across Iceland, where the most exposed locations are already reporting 200-220 km/h wind gusts this morning. Conditions will worsen […]

The exponential growth in computer processing power seen over the past 60 years may soon come to a halt. Complex systems such as those used in weather forecast, for example, require high computing capacities, but the costs for running supercomputers to process large quantities of data can become a limiting factor. Researchers have recently unveiled an algorithm that can solve complex problems with remarkable facility -- even on a personal computer.

As expected, the Northwest and North Atlantic are creating a spectacular show tonight. A very impressive satellite presentation is seen on the explosive cyclogenesis near the Newfoundland this evening, the system has deepened for a remarkable 50 mbar in the past 24 hours – more than a double threshold for rapid intensification/bombogenesis cyclone (-24 mbar […]
