Marine heatwaves:
A new study reveals that tropical cyclones passing over marine heatwaves are far more destructive, resulting in 60% more billion-dollar disasters due to rapid intensification.A marine heatwave (MHW) is a prolonged period of unusually high ocean temperatures in a specific region. They are defined by their duration (lasting several days to months) and intensity (deviations from average sea surface temperatures, known as temperature anomalies).
While exact thresholds vary, an anomaly of 1 degree Celsius to 3 degree Celsius above the long-term average for a particular season is typically characterized as a marine heatwave event.
