Rome, 29 October 2021 – Live images of thehurricane Apollo very clearly show an eye around which, in Counterclockwise, thunderclouds rotate. What does this rotation involve? We asked Manuel Mazzoleni by 3b meteo. “One consequence is definitely that the trajectory it’s not that easy predictable“, explains the meteorologist.
Greater unpredictability
“The rotation in an anti-clockwise direction causes greater unpredictability – explains Mazzoleni – because a series of components are added together. And they can be distributed in a more irregular way than a classic perturbation with a more linear advance front. series of spirals around the low pressure center can give more irregular phenomena. It happens in cyclones that form in thenorthern hemisphere. It is due to the dynamics of the atmosphere and the laws of physics, it is not an anomaly ”.
“These Mediterranean cyclones have already formed in the past in our peninsula. Even if I don’t remember being so close to Sicily, especially to the Syracusan area “.
What happens now
Ma the worst is over? “Today, Friday 29th, is certainly the worst day. Tomorrow Saturday 30th the cyclone will slowly tend to move a little further south. However, he will be able to renew the instability especially in eastern Sicily and part of Ionian Calabria. Then the situation will gradually go away getting better on the weekend. The worst is expected between today and the early hours of tomorrow Saturday 30 November “.
