Two NASA satellites see Tropical Storm Andres intensify

01.06.2015

The first tropical depression of the eastern Pacific Ocean hurricane season strengthened into tropical storm Andres. NASA's Aqua and Global Precipitation Measurement mission core satellite both provided information showing the storm intensifying.

Tropical storm Andres became the first tropical storm of the 2015 Eastern Pacific hurricane season on May 28 at 1500 UTC (11 a.m. EDT). The GPM core observatory satellite flew over the intensifying tropical depression, then known as tropical depression 01E at 1225 UTC (8:25 a.m. EDT).


The MODIS instrument on NASA's Aqua satellite captured this image of Tropical Storm Andres on May 28 at 2100 UTC (5 p.m. EDT), about six hours after it intensified into a tropical storm.

At NASA's Goddard Space Flight Center in Greenbelt, Md., rainfall data from GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (Ku Band) instruments were overlaid on an enhanced GOES-East satellite infrared image to create a three-dimensional picture of the storm.

The data showed that rainfall was occurring at a rate of over 60 mm (2.4 inches) per hour in powerful convective storms near Andres' center. GPM radar data showed tall thunderstorms reaching heights of over 15 km (9.3 miles) in a band of thunderstorms.

Eight and a half hours later, the MODIS, or Moderate Resolution Imaging Spectroradiometer, instrument on NASA's Aqua satellite captured a visible light image of tropical storm Andres. On May 28 at 2100 UTC (5 p.m. EDT), about six hours after it intensified into a tropical storm MODIS data showed Andres took on the signature 'comma shape' of a tropical storm.

The bulk of clouds and showers were south of the center of circulation in a large, thick band of thunderstorms spiraling into the center. The image was created by the MODIS Rapid Response Team at NASA Goddard.

At the same time, the Atmospheric Infrared Sounder ,or AIRS, instrument aboard Aqua captured infrared data. Infrared data indicates temperatures, and the higher the thunderstorms are in the troposphere, the colder the temperature. The colder, higher thunderstorms are more powerful storms with the capability of dropping heavier rainfall.

AIRS measured some cloud top temperatures near the center of circulation at minus 63 degrees Fahrenheit (minues 53 degrees Celsius), and research has shown that those storms can generate heavy rainfall.

At 9 a.m. EDT (1500 UTC), the center of tropical storm Andres was located near latitude 12.5 north and longitude 114.6 west, about 780 miles (1,260 km) south-southwest of the southern tip of Baja, Calif.. Andres is moving toward the west-northwest near 9 mph (15 kph). A northwestward motion at a slightly slower forward speed is expected continue through Saturday night.

Maximum sustained winds remain near 70 mph (110 kph) with higher gusts. Some strengthening is forecast during the next 48 hours, and Andres is expected to become a hurricane later in the day on May 29. Tropical storm force winds extend outward up to 115 miles (185 km) from the center. The estimated minimum central pressure is 994 millibars (29.36 inches).

During the past month the National Oceanic and Atmospheric Administration (NOAA) has observed warmer sea surface temperatures in the eastern Pacific Ocean. This indicates that El Nino is becoming stronger. El Nino usually means stronger hurricane activity in the central and eastern pacific basins so many other tropical cyclones are likely to follow Andres lead in the eastern Pacific.

The National Hurricane Center expects Andres' winds to peak on May 31 near 100 mph before a weakening trend commences. Andres is expected to remain at sea, and move in a northwesterly direction over the next several days.

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:...

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,...
