After a Tropical low pressure, NASA's Aqua satellite spotted some very cold, high, thunderstorms around the center of a tropical low pressure area in the Atlantic Ocean today, indicating that the system is getting stronger,organized and developed.
In that low pressure area, designated as system 99L was located about 850 miles east of the southern Windward Islands near 10.7 north latitude and 46.9 west longitude then it was moving west between 15 and 20 mph.
The Aqua Satellite's Atmospheric Infrared Sounder (AIRS) instrument captured an infrared image of the storm. It showed that there was a small area of strong, high, cold cloud tops of thunderstorms around the center of circulation, indicating some strength in the low pressure area. Infrared imagery shows temperature and the higher the cloud tops, the colder they are as they reach higher in the troposphere (lowest atmospheric layer). When cloud top temperatures are very cold, it's an indication of strong uplift in the atmosphere. The cloud top temperatures around the center of this low were near -63 Fahrenheit (-52 Celsius), and indicated powerful uplift and high cloud tops.
