NASA sees wind shear affecting Hurricane Ignacio

02.09.2015

Hurricane Ignacio is staying far enough away from the Hawaiian Islands to not bring heavy rainfall or gusty winds, but is still causing rough surf. Infrared satellite data on September 1 shows that wind shear is adversely affecting the storm and weakening it.

The Atmospheric Infrared Sounder or AIRS instrument that flies aboard NASA's Aqua satellite gathers infrared data that reveals temperatures. When NASA's Aqua satellite passed over Ignacio on September 1 at 11:41 UTC (7:41 a.m. EDT), the AIRS data and showed some high, cold, strong thunderstorms surrounded the center where cloud top temperatures were near -63F/-53C.


This infrared image from NOAA's GOES-West satellite shows Hurricane Ignacio's clouds bring blown to the northeast from wind shear on Sept. 1 at 8:00 a.m. EDT.

However, AIRS also showed that southwesterly wind shear was pushing the thunderstorms to the northeast of the low-level center.

The National Hurricane Center noted that infrared data showed the central dense overcast clouds had now been completely sheared away and replaced with a "warmer banding feature across the western and northern semicircles." That means weaker thunderstorms with less cold cloud top temperatures, because there wasn't as much uplift in the atmosphere to push them higher.

On September 1 at 8:00 a.m. EDT an infrared image from NOAA's GOES-West satellite clearly showed that that southwesterly vertical wind shear was affecting the storm. In the image it appeared that Ignacio developed a tail that extended to the northeast as its clouds and thunderstorms were being pushed in that direction.

At 11 a.m. EDT (1500 UTC/5 a.m. HST), the center of Hurricane Ignacio was near latitude 23.5 north and longitude 153.7 west. That's about 310 miles (495 km) east-northeast of Honolulu, Hawaii, and 275 miles (445 km) north-northeast of Hilo. The estimated minimum central pressure is 984 millibars.

Ignacio's maximum sustained winds dropped to near 80 mph (130 kph). That means that Kilo is a category one hurricane on the Saffir-Simpson Hurricane wind scale. The Central Pacific Hurricane Center expects Ignacio to slowly weaken through early Thursday, September 3.

NOAA's Central Pacific Hurricane Center noted that large swells generated by Ignacio will continue along east and northeast facing shores of the Hawaiian Islands over the next couple of days. Resultant surf will be large...potentially damaging and life-threatening.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
