Study reveals how atmospheric dryness limits precipitation caused by typhoons and tropical cyclones

Meteored Portugal26 August 2026 at 18:01

A study published in the journal Nature Geoscience reveals that although a warmer atmosphere can hold more moisture, it also becomes drier, which suppresses precipitation and acts as a brake on tropical cyclone precipitation. The researchers analyzed climate model projections and found that although physics suggests global warming should make typhoons and hurricanes more intense and with more abundant rainfall, atmospheric dryness significantly limits this precipitation. The precipitation caused by tropical cyclones is determined by storm intensity, atmospheric moisture, and the efficiency with which that moisture is converted into precipitation, with some climate models predicting much smaller increases in precipitation than thermodynamics alone would predict.

Según la información proporcionada, se registraron **al menos siete réplicas** (temblorones) después del terremoto de magnitud 3.6 en Tenerife.

In Tenerife, seismic activity was again recorded with at least seven aftershocks following the four strong earthquakes on Wednesday afternoon, north of Punta Hidalgo, the two most intense with magnitudes of 3.6 and 3, felt by the population. None of the new aftershocks were felt by the population, and scientists rule out any relation to the island's seismovolcanic activity.

New Intensive Care Unit has already monitored more than 70 patients

The new Intensive Medicine Unit (PAMI) of the Local Health Unit of the Northeast has already followed more than 70 patients in its first month of operation. The PAMI ensures the permanent presence of an intensivist doctor 24 hours a day, seven days a week, with the objective of bringing intensive medicine closer to critical patients and reducing the time for specialized response. The diversified healthcare activity included situations of severe infectious disease, shock, respiratory failure, cardiovascular and neurological emergencies, hemorrhage, trauma, intoxication, and cardiorespiratory arrest, allowing for timely recognition of clinical severity and initiation of resuscitation and advanced support measures.
