NASA-NOAA’s Finnish nuclear power plant sees extratropic Oso damaged by wind shear
Status Report From: NASA Headquarters
Posted: on Thursday, October 8, 2015
Infrared data from NASA-NOAA’s Finnish nuclear power plant satellite showed that tropical storm Weak weakened over cool waters and turned into an extratropic cyclone after severe wind shear.
Infrared data from NASA-NOAA’s Finland NPP satellite’s VIIRS (Visible Infrared Imaging Radiometer Suite) showed that the remaining deep convections, clouds, and rainfall reached far northeast of downtown Oho on October 7, 2217 (6.17). pm EDT). This continued on October 8, when a relentless vertical wind cut of 45 to 55 knots (51.7 to 63.2 mph) continued to affect the storm. In addition, analysis of the vessels showed that the Oso navigated in very cool waters near 22 degrees Celsius. Tropical cyclones require sea level temperatures of at least 26.6 degrees Celsius / 80 Fahrenheit to maintain intensity.
On Thursday, October 8, 2015, at 11:00 AM EDT / 5.00 HST / 1500 UTC, Extra-Tropical Cyclone Oho Center was located near latitude 35.4 N and longitude 141.0 West. The storm is far from the land. It is approximately 1,380 miles (2,225 km) northeast of Hawaii. The extratropic cyclone is moving northeast near 43 mph (69 km / h) and is expected to turn northwest.
Maximum continuous wind speeds are close to 70 mph (110 km / h), and the NOAA’s Central Pacific Hurricane Center forecast that the storm will subside by 9 a.m., then intensify late in the day and subside again on 10 October.
Becoming “extratropic” means that the cyclone has lost its “tropical” properties. The National Hurricane Center defines an “extratropic” transition phase as meaning both the transition of a cyclone to the polar direction (i.e., it moves toward the North or South Pole) and the conversion of a cyclone’s primary energy source from latent condensation heat to baroclinic processes between warm and cold air masses. It is important to note that cyclones can become extratropic and still retain the forces of a hurricane or tropical storm.
The CPHC gave its final advice on Oho. Future information on this system can be found in the Open Sea Forecasts published by the National Weather Service Ocean Prediction Center at: http://www.prh.noaa.gov/hnl/pages/HSFNP.php. Residents of southwestern Canada and the northwestern Pacific of the United States should monitor the progress of this extratropic storm as it is expected to affect the west coast over the weekend of October 10th and 11th.
