Using NASA’s Aqua satellite, scientists have gathered infrared look at the large and powerful Hurricane Florence that demonstrated wind shear was incidentally influencing the southern side of the tempest. The hurricane force winds extend outward up to 80 miles (130 km) from the center and tropical-storm-force winds extend outward up to 195 miles (315 km).
The data gathered by the satellite showed that the clouds in the southern quadrant of Hurricane Florence seemed hotter than storms all through whatever is left of Florence. That implies that the cloud tops are lower in the atmosphere, and the storms are not as powerful.
That is on account of vertical breeze shear, the change of speed and direction of winds with altitude was slamming the southern side of Florence and keeping the advancement of higher, stronger rainstorms in that piece of the storm.
NOAA’s National Hurricane Center (NHC) said “microwave overpass indicated that the convection over the southern and southeastern portions of the storm is still disrupted and that the eyewall was open to the southeast. It appears that some southern shear has caused the degradation of the inner core. The global models suggest that this shear will relax today while Florence moves over warm waters, however, given the current storm structure, little overall change in strength is anticipated as Florence approaches the coast.”
At 2:20 a.m. EDT (0230 UTC) on Sept. 13, Moderate Resolution Imaging Spectroradiometer or MODIS instrument onboard NASA‘s Aqua satellite analyzed Hurricane Florence in infrared light. MODIS discovered coldest cloud top temperatures in a tight band around the eyewall (the tempests encompassing the open eye), as cool as or colder than less 80 degrees Fahrenheit (F)/short 112 degrees Celsius (C). Encompassing the eye were thick rings of intense storms with cloud best as chilly as or colder than short 70F (less 56.6C).
NASA research has found that cloud top temperatures as cold as or colder than the 70F/56.6C threshold have the capability to generate heavy rainfall.
NHC noted Storm Surge Warning is in effect for South Santee River, South Carolina to Duck, North Carolina and for the Albemarle and Pamlico Sounds, including the Neuse and Pamlico Rivers. A Storm Surge Watch is in effect for Edisto Beach South Carolina to South Santee River, South Carolina and north of Duck, North Carolina to the North Carolina/Virginia border.
