NASA Sees Some Strength in Tropical Storm Patty's Brief Debut

15.10.2012
Tropical Depression 16 formed on Oct. 11 and by 5 p.m. EDT that same day, it strengthened into Tropical Storm Patty. NASA's TRMM and Terra satellite's captured imagery on Patty's rainfall intensity and cloud heights, both of which showed strong, high thunderstorms around the center of circulation.

On Oct. 11 at 11 a.m. EDT the National Hurricane Center (NHC) announced the formation of tropical depression sixteen (TD16) northeast of the Bahamas. Earlier, at 0422 UTC (12:22 a.m. EDT), the Tropical Rainfall Measuring Mission (TRMM) satellite had a look at the disturbed weather associated with the formation of TD16. TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) indicated that surface precipitation was falling at a rate of up to 20mm per hour (~0.8 inches per hour) in the northwestern part of this small area of low pressure.

TRMM precipitation radar data was used to create a 3-D view of the storm that showed that a few of the most powerful convective storms called "hot towers" in the developing tropical depression were reaching altitudes of over 16km (~9.9 miles). NASA research has shown that whenever hot towering thunderstorms are spotted within a tropical cyclone, the storm intensifies within about six hours, and the low pressure area did, becoming Tropical Depression 16. It also intensified further into Tropical Storm Patty by 5 p.m. EDT that day.

The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard NASA's Terra satellite also captured a visible image of Tropical Depression 16 on Oct. 11. Terra passed over Tropical Depression 16 at 1515 UTC (11:15 a.m. EDT) just six hours before it strengthened into Tropical Storm Patty. Strongest storms around the center cast shadows on lower surrounding thunderstorms indicating that the storm continued to generate a large mass of deep convection.

On Friday, Oct. 12, Patty was drifting at 3 mph (6 kph) south-southwestward near the Bahamas and was already weakening. Tropical Storm Patty had maximum sustained winds near 40 mph (65 kph). Patty's center was located near 25.1 North latitude and 72.5 West longitude, about 230 miles (375 km) east-northeast of the central Bahamas. The National Hurricane Center (NHC) expects Patty to move slowly to the south-southwest or southwest and speed up on Sunday, Oct. 14 while continuing to weaken. In fact, the NHC noted that Patty could become a remnant low pressure area on Saturday, Oct. 13.

Dry and more stable air wrapping around Tropical Storm Patty is the factor that is expected to weaken the storm. The NHC forecasters noted that a low-level ridge (elongated area) of high pressure is building up (strengthening) over the western Atlantic Ocean, and that's going to increase the winds shear from the southwest over the weekend of Oct. 13 and 14, so Patty is likely going to be blown apart in the next day or two.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
