Unique hurricane transition close to Europe

By reaching Category 3 intensity hurricane Ophelia has become the strongest hurricane ever observed so far in the east in the Atlantic Ocean. We could even observe the eye as close to the western European shore as never before. Above all, this hurricane underwent so-called transition to the common midlatitude cyclone. This process can be […]

Tropical cyclone named Irma is moving from west coast of Africa toward North America and is still strengthening.

Another severe thunderstorm outbreak over Slovakia

A thunderstorm developing in vertical wind shear is quite rare in Bratislava, especially during the summer season. However, this year has brought us many of them, for example on Sunday 27th August. The 12:00 pm UTC Vienna sounding (approximately 60 km from Bratislava to the west) shows moderate CAPE and a very low CIN, despite […]

The old […]

Temperature at 850 hPa level reached -20°C above Poprad aerological station, which is a very rare value within the last 25 years.As the cold air flows to the south over the Baltic Sea, temperature […]

The most common temperature stratification during winter in the central Europe is an inversion – i.e. temperature of air increases with height. The best way to visualize these situations are vertical cross sections and thermodiagrams. Figure 1 – Vertical change of temperature (solid line) and dew point (dashed line) in Wien on Dec 19th (blue), […]

According to theory, the most typical circulation difference between mid- and tropical latitudes is there is almost no vertical wind shear in the tropics, i.e. there is the same wind speed and direction with the height. However, situation is much more complex in the reality. Nice example of the tropical weather complexity is the Southeast […]
