A satellite image of Tropical Storm Jasper taken on December 12, 2023 by the Moderate Resolution Imaging Spectroradiometer aboard NASA’s Aqua satellite.
The first storm of Australia’s tropical cyclone season has headed towards Port Douglas.
The 2023 tropical cyclone season will occur in the Atlantic Ocean and Northeast Pacific Ocean. nearing the end, but in the southern hemisphere near Australia, it’s just getting started. The region’s first tropical cyclone of the season formed in the first week of December in the Coral Sea.
MODIS (Moderate Resolution Imaging Spectroradiometer) NASA‘s Aqua satellite captured images of Tropical Cyclone Jasper approaching northeast Queensland on December 12 at 04:10 UTC (3:10 p.m. local time).
With maximum wind speeds of 220 kilometers per hour (140 mph), the storm had earlier intensified rapidly, reaching Category 4 strength in the upper atmosphere. saffir simpson scale. It then weakened under the influence of dry air and wind, preventing a more symmetrical structure and clearer eyes by the time this image was taken.
with the forecaster Joint Typhoon Warning Center Jasper is expected to strengthen slightly on its final approach and make landfall near Port Douglas with winds of 120 kilometers per hour (75 miles per hour), making it a weak Category 1 storm.In some areas you can receive up to 30cm The Australian Bureau of Meteorology said 12 inches of rain fell in six hours and up to 50 centimeters in 24 hours.
Used by forecasters at the Joint Typhoon Warning Center observation From NASA’s TROPICS (Time-Resolved Observation of Precipitation Structure and Storm Intensity by Small Satellites) mission. their analysis The strength of the storm before landfall. Tracking storms with TROPICS is expected to improve our understanding of the processes that cause the rapid intensification of tropical cyclones. Each of his five satellites in this constellation carries a cross-track microwave sounder that makes observations at 205 gigahertz, which improves observations of storm cloud structure.
among them Announcement of seasonal outlook In October, the Australian Bureau of Meteorology predicted that Australia would have fewer tropical cyclones than usual this season. El Niño.Satellite observations collected since the 1970s It shows that the number of such storms forming near Australia is gradually decreasing.of Sixth Assessment Report More from the Intergovernmental Panel on Climate Change Projects downward trend In the future, the frequency of tropical cyclones in Australia will increase, but the proportion of severe storms will increase.
