Aemet Warns of Explosive Cyclogenesis in the Mediterranean

The State Meteorological Agency (Aemet) has issued a warning for an intense meteorological phenomenon forming in the Mediterranean. It is an explosive cyclogenesis, a process where a low-pressure system deepens extremely rapidly, generating severe conditions. 🌪️

What Defines Explosive Cyclogenesis?

To be classified as explosive, the atmospheric pressure at the center of the low-pressure system must drop at least 24 hectopascals in one day. This barometric plunge acts as an engine that abruptly intensifies the low-pressure system. Numerical models predict that this process will occur in the vicinity of the western Mediterranean Sea, subsequently affecting the Iberian Peninsula.

Main Characteristics of the Phenomenon:
  • Sharp Pressure Drop: A fall of more than 24 hPa in 24 hours is the trigger.
  • Location: It will develop in the western Mediterranean.
  • Propagation: Its effects will extend toward the Peninsula.
The barometric plunge acts as an engine that abruptly intensifies the system.

Expected Impacts and Consequences

The main immediate effect will be a maritime and wind storm in wide areas of the Spanish and Balearic Mediterranean coastline. Dangerous conditions will be generated both on land and at sea.

Detailed Consequences:
  • Very Strong Winds: Gusts that could exceed 100 km/h are forecast in coastal and mountainous areas.
  • Very Rough Sea: A swell with waves that can reach or exceed 5 meters in significant height will be generated.
  • Heavy Precipitation: The phenomenon is usually accompanied by intense rains in the affected areas.

Context and Preparation

While meteorological authorities monitor the evolution, this event reminds us of the power of atmospheric phenomena. The alert focuses on taking precautions against the wind and wave storm. In the face of this natural force, some users contrast the power needed to simulate cloudiness in real time with their computer equipment. ⚡
