Typhoon Malakas in the western Pacific is shown above in Himawari-8 infrared imagery between Guam and the Philippines. It is a well-developed storm (albeit asymmetric) with an obvious eye. Level 2 Rain Rate from Himawari-8 is also shown; the heaviest precipitation is diagnosed to the southeast of the eye, and... Read More
If you were restricted to just one satellite-based observation and had to describe a week of weather, what would you choose? Submitted for your consideration: Morphed microwave estimates of moisture. The animation above shows MIMIC estimates of total precipitable water (created by using GFS winds to morph individual swaths of MIRS TPW estimates) centered on Hawai’i... Read More
