Cyclone Chapala captured early Monday morning by NOAA's Aqua satellite.
Tropical cyclones can cause devastating and lethal damage to East and Southeast Asian countries.
But accurately tracking changes in the frequency and intensity of typhoons is challenging in part because the data on these storms hasn t always been consistently kept, and in part because there s simply a lot of variability in the number of storms that make landfall.
In a recent issue of Nature Geoscience, new cluster and bias-corrected analyses of storm data show that the intensity and frequency of these dangerous storms have increased considerably.
The authors of this paper focused on typhoons that strike East Asia, which limits the analysis to the northwest Pacific Ocean.
They used a regional cluster analysis to probe the storm data, grouping the cyclones according to the part of the ocean where they formed and their movement patterns.
