A tropical low pressure area known as System 92B has been organizing in the Northern Indian Ocean's Bay of Bengal and NASA's TRMM satellite has shown strong thunderstorms and heavy rainfall in the developing storm.
The Tropical Rainfall Measuring Mission or TRMM satellite passed over System 92B on May 19 and 20 and captured data on System 92B's rainfall rates and cloud heights.
On May 19, 2014 at 1056 UTC (6:56 a.m. EDT) TRMM flew over a tropical low (92B) in the Bay of Bengal east of India. TRMM's Precipitation Radar (PR) instrument found that rain was falling at a rate of over 138 mm (about 5.4 inches) per hour in some strong convective storms.
At NASA's Goddard Space Flight Center in Greenbelt, Maryland, TRMM PR data were used to create a 3-D image that showed a simulated view of the tropical disturbance's rainfall structure. In the 3-D image, tall storms were shown reaching heights of over 14km (about 8.7 miles) and returning reflectivity values of over 52dBZ to the satellite.
TRMM had another fairly good look at 92B on May 20 at 1000 UTC (6:00 a.m. EDT). TRMM's Microwave Imager (TMI) had a better view than the PR instrument that flew over the northern edge of 92B. TMI showed that 92B was better organized than previously and estimated that rain was falling at a rate of over 33.8 mm (1.3 inches) per hour in some areas.
The Joint Typhoon Warning Center or JTWC noted that a microwave image from Europe's METOP-B satellite on May 21 at 04:54 UTC (12:54 a.m. EDT) showed that the bulk of strong thunderstorms and deep convection in System 92B was over the storm's southern quadrant and wrapping into the low-level center.
On May 21 at 07:30 UTC/3:30 a.m. EDT the JTWC gave System 92B a high chance for development. At that time the center of circulation was near 16.1 north latitude and 91.4 east longitude, about 375 nautical miles south of Chittagong, Bangladesh.
Another instrument on METOP-B looked at the developing storm's winds. The prime objective of Advanced SCATterometer (ASCAT) is to measure wind speed and direction over the oceans. An image from ASCAT on May 21 at 03:57 UTC showed that the circulation of 92B appeared elongated, with 35 to 40 knot winds over the southwestern quadrant and weaker winds (15 to 20 knots) over the northern semi-cicle.
JTWC noted that the warm sea surface temperatures in the area will help with development.

In a survey of NASA's Hubble Space Telescope images of 2,753 young, blue star clusters in the neighboring Andromeda galaxy (M31), astronomers have found that M31 and our own galaxy have a similar percentage of newborn stars based on mass.
By nailing down what percentage of stars have a particular mass within a cluster, or the Initial Mass Function (IMF), scientists can better interpret the light...

China's Loess Plateau was formed by wind alternately depositing dust or removing dust over the last 2.6 million years, according to a new report from University of Arizona geoscientists. The study is the first to explain how the steep-fronted plateau formed.

The leaves of the lotus flower, and other natural surfaces that repel water and dirt, have been the model for many types of engineered liquid-repelling surfaces. As slippery as these surfaces are, however, tiny water droplets still stick to them. Now, Penn State researchers have developed nano/micro-textured, highly slippery surfaces able to outperform these naturally inspired coatings, particularly when the water is a vapor or tiny droplets.
Enhancing the mobility of liquid droplets on rough surfaces could improve condensation heat transfer for power-plant heat exchangers, create more efficient...
Longer, more severe, and hotter droughts and a myriad of other threats, including diseases and more extensive and severe wildfires, are threatening to transform some of the world's temperate forests, a new study published in Science has found. Without informed management, some forests could convert to shrublands or grasslands within the coming decades.
"While we have been trying to manage for resilience of 20th century conditions, we realize now that we must prepare for transformations and attempt to ease...
