On March 10, the Core Observatory passed over an extra-tropical cyclone about 1055 miles (1700 kilometers) due east of Japan's Honshu Island. The storm formed from the collision of a cold front wrapping around a warm front, emerging over the ocean near Okinawa on March 8. It moved northeast over the ocean south of Japan, drawing cold air west-to-east over the land, a typical winter weather pattern that also brought heavy snow over Hokkaido, the northernmost of the four main islands. After the GPM images were taken, the storm continued to move eastward, slowly intensifying before weakening in the central North Pacific.This visualization shows data from the GPM Microwave Imager, which observes different types of precipitation with 13 channels. Scientists analyze that data and then use it to calculate the light to heavy rain rates and falling snow within the storm.For more information on this topic: GPM web siteOther multimedia items related to this story: GPM GMI First Light (#11508) GPM DPR First Light (#11509) || ", "hits": 36 }, { "id": 11508, "url": "https://svs.gsfc.nasa.gov/11508/", "result_type": "Produced Video", "release_date": "2014-03-25T01:00:00-04:00", "title": "GPM GMI First Light", "description": "On March 10, the Core Observatory passed over an extra-tropical cyclone about 1055 miles (1700 kilometers) due east of Japan's Honshu Island.

This light lost energy as the universe expanded over 13.7 billion years, so WMAP now sees the light as microwaves.

TRMM has five Earth-observing instruments on board and circles the Earth every 92 minutes in an equatorial orbit between 35 degrees north and south latitude so that those instruments can measure precipitation in the tropics. One of the instruments, TMI, observes five frequencies of microwave emissions in a 780-kilometer wide swath along the orbit in order to measure the amount of rain and ice in the atmosphere. This animation shows the TRMM satellite orbiting for one day, August 27, 2005, showing a set of TRMM measurements at a frequency of 85.5 GHz. In this frequency band, atmospheric ice crystals scatter microwaves and so areas with ice crystals appear colder than areas with no ice. Both Hurricane Katrina, just to the west of Florida in the Gulf of Mexico, and Typhoon Talim, in the westerm Pacific between Japan and New Guinea, show up as bright swirling patterns. This measurement is just one of the TMI measurements that go into calculating the total instantaneous rainfall in the tropics. || ", "hits": 26 }, { "id": 3248, "url": "https://svs.gsfc.nasa.gov/3248/", "result_type": "Visualization", "release_date": "2005-10-19T00:00:00-04:00", "title": "TRMM Microwave Brightness Temperature Progression During Hurricane Katrina: Horizontal Polarization", "description": "The TMI instrument on the TRMM satellite measures microwaves emitted from the Earth's land and water.
