NASA-NOAA satellite provides wide view of Tropical Cyclone Oma

February 22, 2019

When you look at a Tropical Cyclone Oma from space, you'll get a sense of its massive size. While orbiting the Earth, NASA-NOAA's Suomi NPP satellite provided a look at the large tropical storm in the Southern Pacific Ocean.

Oma weakened rapidly from a typhoon to a tropical storm, and on Feb 22, the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA's Suomi NPP satellite captured a visible image of Oma. The VIIRS image also showed a long the bulk of clouds and thunderstorms pushed into the storm's southern quadrant, looking like a large tail. That's because northeasterly winds, or northeasterly vertical wind shear is pushing the clouds and tearing the storm apart. The Joint Typhoon Warning Center noted that rain bands, bands of thunderstorms that feed into the center, are unraveling, and the storm is elongating. Whenever a storm is no longer circular and elongates, it is a sign of weakening.

At 10 a.m. EDT (1500 UTC) the Joint Typhoon Warning Center or JTWC noted that Oma's maximum sustained winds dropped to 35 knots (40 mph). Oma's center was located near 27.7 degrees south latitude and 159.9 east longitude, that's approximately 367 nautical miles east of Brisbane, Australia. Oma has tracked south and is forecast to turn to the north and is expected to dissipate in a day or two.

#521 The Curious Life of Krill
Krill may be one of the most abundant forms of life on our planet... but it turns out we don't know that much about them. For a create that underpins a massive ocean ecosystem and lives in our oceans in massive numbers, they're surprisingly difficult to study. We sit down and shine some light on these underappreciated crustaceans with Stephen Nicol, Adjunct Professor at the University of Tasmania, Scientific Advisor to the Association of Responsible Krill Harvesting Companies, and author of the book "The Curious Life of Krill: A Conservation Story from the Bottom of the World".
