Cyclone Freddy in Southeast Africa

Cyclone "Freddy" was recently raging over Southeast Africa. The tropical cyclone was causing havoc in Malawi and Mozambique. Find more information about cyclone "Freddy" and general facts about cyclones.

An image of our satellite map from 13-03-2023 shows how the cyclone was moving across the region.

Tropical storm "Freddy" has been raging in Southeast Africa on 13-03-2023. It hit the region of East Africa for the second time in just a few weeks, whereas the first time is also reported in our weather news. Locally, it caused stormy weather conditions with lots of rain and strong winds. Therefore, we recommend our precipitation map or weather radar to track such events since they show real-time weather conditions.

The heavy rains are also visible in our weather archive. In addition, the weather archive offers historical simulation data for every place worldwide, summarising the most important weather information.

We want to use this storm to explain a cyclone in more detail.

Generally, a cyclone can be described as a fast-rotating storm developing over the Indian Ocean. You can track the storm with our wind animation, providing a 7-day forecast. It is a storm accompanied by low atmospheric pressure, high winds, and heavy rain, usually creating destruction when hitting the land surface. Cyclones are the pendant to heavy storms in the North Atlantic Ocean, the so-called Hurricanes, or the typhoons in the northwestern Pacific Ocean.

Due to high water temperatures in tropical oceans, water begins to vapour.

As the water vapour rises, it condensates, and clouds form. The rising of warm air creates low pressure over the ocean. Air always moves from high-pressure to low-pressure areas, which also creates wind. Under strong vapouring conditions, pressure sinks more. Therefore more (and warm) air from high-pressure regions moves towards the low-pressure centre. Steadily, warm moist air rises, creating even more dense clouds. As can be seen well in our satellite images, the clouds drift towards the low-pressure centre, the "eye" of the cyclone. Since cyclone Freddy was in the southern hemisphere, air masses rotate clockwise, caused by the earth's rotation. Finally, global winds move the cyclone back and forth, and, as in the case of Freddy, cyclones can therefore travel many kilometres.

Freddy carried much energy, high wind speeds and much moisture. Especially its long lifetime is a peculiarity. In times of climate change, the intensification of storms like these is also expected in the future.
