Hurricane Norbert Pinwheels in NASA Satellite Imagery


The Eastern Pacific's Hurricane Norbert resembled a pinwheel in an image from NASA's Terra satellite as bands of thunderstorms spiraled into the center. NASA's Global Precipitation Measurement or GPM mission has helped forecasters see that Norbert has lost some of its organization early on September 4.

The MODIS instrument or Moderate Resolution Imaging Spectroradiometer aboard NASA's Terra satellite captured a visible picture of Tropical Storm Norbert on Sept. 4 at 2:15 p.m. EDT when it resembled a pinwheel. The western bands of Norbert were moving over Socorro Island, located several hundred miles west of Mexico's west coast. An eye was not apparent in the image, although Norbert was strengthening into a hurricane. The image was created by the MODIS Rapid Response Team at NASA's Goddard Space Flight Center in Greenbelt, Maryland.

Less than six hours later at 8 p.m. EDT, the National Hurricane Center noted that Norbert became a hurricane with maximum sustained winds near 75 mph (120 kph). Overnight and into the early morning hours of September 4, maximum sustained winds increased to 80 mph (130 kph).

On Thursday, September 4, 2014, the National Hurricane Center (NHC) continued the Tropical Storm Warning from La Paz to Cabo San Lazaro, Mexico. A tropical storm watch is also in effect north of Cabo San Lazaro to Puerto San Andresito and north of La Paz to San Evaristo.

At 8 a.m. EDT (5 a.m. PDT), Norbert's maximum sustained winds remain near 80 mph (130 kph) and some slow strengthening is expected during the next 24 hours. Those hurricane-force winds only extend up to 25 miles (35 km) from the center, and tropical storm force winds extend out 105 miles (165 km), which is why the Baja is under a tropical storm warning.   

Norbert's center was located near latitude 20.6 north and longitude 110.0 west. That's just 160 miles (255 km) south of the southern tip of Baja California. Norbert was moving toward the northwest near 6 mph (9 kph) and movement in that direction is expected to continue over the next couple of days taking Norbert along the coast.

On the NHC's forecast track the center of the hurricane is expected to approach the southern tip of the Baja California Peninsula today and move nearly parallel to the pacific coast of the peninsula tonight and Friday, September 5.

The NHC uses data from multiple satellites, including NASA's new GPM satellite. The NHC discussion on Norbert at 5 a.m. EDT today, September 4, said "Recent microwave images, including a NASA GPM overpass at 0516 UTC (1:16 a.m. EDT), indicate that Norbert has lost some organization during the past few hours due to easterly vertical wind shear.  The low-level center is in the northeastern part of the central convection with a mid-level eye displaced to the southwest of the low-level center.

Norbert is forecast to track parallel along the coast of Baja California for the next couple of days.

Im Focus: How Cells in the Developing Ear ‘Practice’ Hearing

Before the fluid of the middle ear drains and sound waves penetrate for the first time, the inner ear cells of newborn rodents practice for their big debut. Researchers at Johns Hopkins report they have figured out the molecular chain of events that enables the cells to make “sounds” on their own, essentially “practicing” their ability to process sounds in the world around them.

The researchers, who describe their experiments in the Dec. 3 edition of the journal Cell, show how hair cells in the inner ear can be activated in the absence...

Im Focus: Climate study finds evidence of global shift in the 1980s

Planet Earth experienced a global climate shift in the late 1980s on an unprecedented scale, fuelled by anthropogenic warming and a volcanic eruption, according to new research published this week.

Scientists say that a major step change, or ‘regime shift’, in the Earth’s biophysical systems, from the upper atmosphere to the depths of the ocean and from...

Im Focus: Lactate for Brain Energy

Nerve cells cover their high energy demand with glucose and lactate. Scientists of the University of Zurich now provide new support for this. They show for the first time in the intact mouse brain evidence for an exchange of lactate between different brain cells. With this study they were able to confirm a 20-year old hypothesis.

In comparison to other organs, the human brain has the highest energy requirements. The supply of energy for nerve cells and the particular role of lactic acid...

Im Focus: Laser process simulation available as app for first time

In laser material processing, the simulation of processes has made great strides over the past few years. Today, the software can predict relatively well what will happen on the workpiece. Unfortunately, it is also highly complex and requires a lot of computing time. Thanks to clever simplification, experts from Fraunhofer ILT are now able to offer the first-ever simulation software that calculates processes in real time and also runs on tablet computers and smartphones. The fast software enables users to do without expensive experiments and to find optimum process parameters even more effectively.

Before now, the reliable simulation of laser processes was a job for experts. Armed with sophisticated software packages and after many hours on computer...
