NASA sees Tropical Depression 03W's 'hot tower' on approach to Guam

22.05.2012
NASA's Tropical Rainfall Measuring Mission satellite has caught two tropical cyclones with "hot towers" this week, and that's a hallmark that they'll intensify. Tropical Depression 03W is approaching Guam and is expected to strengthen.

"Hot Tower" rain clouds within a tropical cyclone indicate that the storm is going to intensify, and that's what NASA's TRMM satellite spotted in newborn Tropical Depression 2E in the eastern Pacific Ocean and now in Tropical Depression 03W (TD03W) in the western North Pacific Ocean.


When NASA's TRMM satellite passed over TD03W on May 21, 2012, at 0642 UTC (2:42 a.m. EDT), data revealed a hot tower over 15 kilometers (9.3 miles) high. TRMM also measured rainfall within the tropical depression, and found that isolated areas of heavy rain (falling at a rate of 2 inches/50 mm per hour (appearing in red)) were seen in the western quadrant of the storm. Light to moderate rainfall was falling at a rate between .78 inches and 1.57 inches per hour (20 to 40 mm).

A "hot tower" as a rain cloud that reaches at least to the top of the troposphere, the lowest layer of the atmosphere. 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.

When NASA's TRMM satellite passed over TD03W on May 21, 2012 at 0642 UTC (2:42 a.m. EDT), data revealed a hot tower over 15 kilometers (9.3 miles) high. That's an indication that the storm is going to intensify, and that's one factor that forecasters at the Joint Typhoon Warning Center are using in their forecast, which calls for TD03W to become a tropical storm.

TRMM also measured rainfall within the tropical depression, and found that isolated areas of heavy rain (falling at a rate of 2 inches/50 mm per hour) were seen in the western quadrant of the storm. Light-to-moderate rainfall was falling throughout the rest of the storm.

Tropical Depression 03W is close to Guam, just 160 nautical miles south-southeast of Andersen Air Force Base, Guam, near 10.8 North and 145.9 East. It is bringing rain and gusty winds and will continue to do so as it tracks to the west of Guam over the next couple of days and swings to the northeast. Maximum sustained winds are near 25 knots with higher gusts. TD03W is moving to the west, but is expected to turn to the northeast in a couple of days.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
