One of the ways NASA researches tropical cyclones is using infrared data that provides temperature information. ... summer 2020 … Basically, IMERG fills in the blanks between weather observation stations. NASA brings together technology, science, and unique global Earth observations to provide societal benefits and strengthen our nation. Those towering thunderstorms have the potential for heavy rain. Not hurricane Marie. At 5 a.m. EDT (0900 UTC), NOAA's National Hurricane Center (NHC) reported Hurricane Marie was a Category 4 storm on the Saffir-Simpson Hurricane Wind Scale. Estimating Maria’s Rainfall Rates from Space. A “hot tower” is a tall cumulonimbus cloud that reaches at least to the top of the troposphere, the lowest layer of the atmosphere. The remains of the deep convection associated with Marie continues to get further displaced from the exposed low-level center due strong upper-level westerly winds, with the gap now over 100 nautical miles between those two features. Satellite images and tracking maps of Category 4 Major Hurricane Marie 2020, September … NASA’s Integrated Multi-satellitE Retrievals for GPM or IMERG, which is a NASA satellite rainfall product, estimated on Oct. 2 at 4:30 a.m. EDT (0830 UTC), Hurricane Maria was generating as much as 50 mm (2 inches) of rain in the eyewall, ringing around the eye. What IMERG does is “morph” high-quality satellite observations along the direction of the steering winds to deliver information about rain at times and places where such satellite overflights did not occur. This near-real time rainfall estimate comes from the NASA’s IMERG, which combines observations from a fleet of satellites, in near-real time, to provide near-global estimates of precipitation every 30 minutes. Maximum sustained winds have decreased to near 45 mph (75 kph) with higher gusts. Infrared and water vapor data from NASA’s Aqua, Terra and NASA-NOAA’s Suomi NPP satellite were used to help forecasters assess the environment where Marie was headed. Hurricane-force winds extend outward up to 25 miles (35 km) from the center and tropical-storm-force winds extend outward up to 125 miles (205 km). Marie is the third major hurricane (Category 3+) of the Eastern Pacific 2020 season. At 11 a.m. EDT (1500 UTC), the center of Tropical Storm Marie was located near latitude 22.1 degrees north and longitude 135.1 degrees west. Infrared imagery revealed that powerful thunderstorms circled the eye of the hurricane as it moved through the Eastern Pacific Ocean. Rapid strengthening is forecast by the National Hurricane Center. She may have been overhyped but there were definitely some fun waves to be had. Hurricane Marie (2020) Back to the Tropical Center. Hurricane-force winds extend outward up to 15 miles (30 km) from the center and tropical-storm-force winds extend outward up to 70 miles (110 km). NASA infrared imagery revealed that Hurricane Marie is rapidly growing stronger and more powerful. Tropical Depression: … Rainfall throughout most of the storm and in bands of thunderstorms west of the center was occurring at a rate of between 2 and 15 mm (0.08 to 0.6 inches) per hour. NASA satellite imagery has shown that Marie’s structure has been gradually improving. Meteorologist Ari Sarsalari explains how the storm was able to strengthen into a category 4 in such a short period of time. NASA’s Goddard Space Flight Center. Infrared imagery revealed that powerful thunderstorms circled the eye of the hurricane as it moved through the Eastern Pacific Ocean.
