TRMM not only measures rainfall intensity from space but can also give scientists an idea about the height of a thunderstorm that is generating the rainfall within the tropical cyclone. Tropical cyclones are made up of hundreds of thunderstorms.
A "hot tower" is a rain cloud that reaches at least to the top of the troposphere, the lowest layer of the atmosphere. It extends approximately nine miles (14.5 kilometers) high in the tropics. These towers are called "hot" because they rise to such altitude due to the large amount of latent heat. Water vapor releases this latent heat as it condenses into liquid.
On May 20 at 0714 UTC (3:14 a.m. EDT) TRMM flew over Laila after it made landfall in India and captured an image of its rainfall rates. The heaviest rainfall appeared just southeast of the center of circulation, and over land (along the coast). That area was generating rainfall of about 2 inches per hour.
Rain rates are created from different instruments aboard TRMM. The rain rates in the center of TRMM images are derived from the TRMM Precipitation Radar, the only space borne radar of its kind, while those in the outer portion are from the TRMM Microwave Imager. The rain rates are then overlaid on infrared data from the TRMM Visible Infrared Scanner to create the entire image. The images are created at NASA's Goddard Space Flight Center, in Greenbelt, Md.
At 9:00 UTC (5 a.m. EDT) Laila had maximum sustained winds near 50 knots (57 mph). The center of Tropical Storm Laila was close to the town of Bapatla. Bapatla is one of the historical towns and mandals of Guntur District (Andhra Pradesh) located 40 miles south of Guntur City on the East Coast of India. It is also about 220 nautical miles west-southwest of Visakhapatnam, near 16.0 North and 80.1 East.
Laila was moving north-northwestward at 10 knots (12 mph). The Joint Typhoon Warning Center noted that as Laila "follows this path it will encounter the rugged terrain of northeastern Andhra Pradesh and weaken. However, a formidable remnant low is expected to reemerge over the northern Bay of Bengal after 72 hours and accelerate east-northeastward toward eventual landfall over or near south-eastern Bangladesh."
Residents along coastal areas of Andhra Pradesh and Telangana in other areas in Laila's path can expected widespread heavy rainfall and gusty winds. Seas will also be rough, and fishermen were advised by the India Meteorological Department to stay out of the ocean.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...

Scientists at Helmholtz Zentrum München have discovered a mechanism that amplifies the autoimmune reaction in an early stage of pancreatic islet autoimmunity prior to the progression to clinical type 1 diabetes. If the researchers blocked the corresponding molecules, the immune system was significantly less active. The study was conducted under the auspices of the German Center for Diabetes Research (DZD) and was published in the journal ‘Science Translational Medicine’.
Type 1 diabetes is the most common metabolic disease in childhood and adolescence. In this disease, the body's own immune system attacks and destroys the...
