Satellite View of a Hyperactive Eastern and Central Pacific Ocean

05.08.2014

NASA and NOAA satellites have been supplying forecasters with data developing tropical cyclones in the Eastern and Central Pacific Ocean and over the last several days.

There have been as many as five tropical systems at the same time. On Monday, August 4, there were three tropical systems stretching from west to east: Tropical Depression Genevieve in the Central Pacific, Hurricane Iselle and Tropical Storm Julio in the Eastern Pacific.

Tropical Depression Genevieve May Strengthen

On August 4, Tropical Depression Genevieve was located about 930 miles (1,495 km) southwest of Honolulu, Hawaii. Maximum sustained winds were still near 35 mph (55 kph). Genevieve was moving westward at about 16 mph (26 kph). NOAA's Central Pacific Hurricane Center forecasts gradual strengthening late on August 4 and 5, so Genevieve could once again reach tropical storm status.

To the east of Genevieve lies low pressure area known as System 93C. It is producing disorganized showers and thunderstorms. System 93C is located about 500 miles south of Hilo, Hawaii. This low pressure area is moving to the west at 15 mph and currently has a near zero percent chance of becoming a tropical depression over the next couple of days.

Hawaii on Guard for Hurricane Iselle 

Behind System 93C to the east, lies Hurricane Iselle, the current powerhouse of the Eastern Pacific.

The Moderate Resolution Imaging Spectroradiometer or MODIS instrument that flies aboard NASA's Aqua satellite captured a clear visible image of Hurricane Iselle in the eastern Pacific Ocean on August 3 at 6:05 p.m. EDT. The image revealed Iselle's somewhat cloud-covered eye with bands of thunderstorms wrapping into the center from the eastern quadrant. The image was created by The MODIS Rapid Response Team at NASA's Goddard Space Flight Center in Greenbelt, Maryland.

On August 4 at 1500 UTC (11 a.m. EDT) Hurricane Iselle's maximum sustained winds had increased to near 140 mph (220 kph) Iselle is a category four hurricane on the Saffir-Simpson hurricane wind scale. The eye of Hurricane Iselle was located near latitude 16.2 north and longitude 136.5 west.  Iselle was moving toward the west near 10 mph (17 kph). The National Hurricane Center noted that gradual weakening is forecast during the next couple of days. The estimated minimum central pressure is 947 millibars.

The current forecast track from the National Hurricane Center takes a weaker Iselle through the entire chain of Hawaiian Islands from August 7 through August 9.

Newborn Tropical Storm Julio Chasing Iselle

Tropical Storm Julio was born around 11 p.m. EDT on Sunday, August 3, about 795 miles (1,280 km) southwest of the southern tip of Baja California, Mexico.

On August 4 at 1500 UTC (11 a.m. EDT), Julio's maximum sustained winds were near 45 mph (75 kph). The center of Tropical Storm Julio was near latitude 13.5 north and longitude 119.4 west. Julio is moving toward the west near 13 mph (20 kph) and is expected to continue in a west to west-northwestward direction over the next couple of days. The estimated minimum central pressure is 1004 millibars.

Strong northeasterly vertical wind shear is pushing the strongest thunderstorms in Julio to the western side of the storm. The National Hurricane Center noted that the wind shear is expected to continue to August 5 or 6, which will limit any intensification. NHC expects Julio to become a hurricane later this week.

Satellites from NASA and NOAA continue to provide visible, infrared, microwave data to forecasters. Beginning in August, NASA's Hurricane Severe Storms Sentinel or HS3 mission takes to the Atlantic using two unmanned Global Hawk aircraft to study the storms.

Im Focus: Nuclear Pores Captured on Film

Using an ultra fast-scanning atomic force microscope, a team of researchers from the University of Basel has filmed “living” nuclear pore complexes at work for the first time. Nuclear pores are molecular machines that control the traffic entering or exiting the cell nucleus. In their article published in Nature Nanotechnology, the researchers explain how the passage of unwanted molecules is prevented by rapidly moving molecular “tentacles” inside the pore.

Using high-speed AFM, Roderick Lim, Argovia Professor at the Biozentrum and the Swiss Nanoscience Institute of the University of Basel, has not only directly...

Im Focus: 2+1 is Not Always 3 - In the microworld unity is not always strength

If a person pushes a broken-down car alone, there is a certain effect. If another person helps, the result is the sum of their efforts. If two micro-particles are pushing another microparticle, however, the resulting effect may not necessarily be the sum their efforts. A recent study published in Nature Communications, measured this odd effect that scientists call “many body.”

In the microscopic world, where the modern miniaturized machines at the new frontiers of technology operate, as long as we are in the presence of two...

Researchers from the Max Planck Institute Stuttgart have developed self-propelled tiny ‘microbots’ that can remove lead or organic pollution from contaminated water.

Im Focus: ORNL researchers discover new state of water molecule

Neutron scattering and computational modeling have revealed unique and unexpected behavior of water molecules under extreme confinement that is unmatched by any known gas, liquid or solid states.
