Huge post-tropical Hurricane Igor drenched Newfoundland, Canada

23.09.2010
Hurricane Igor may have transitioned into a post-tropical hurricane late yesterday, but when he approached Newfoundland, Canada and merged with an area of low pressure it resulted in heavy rainfall throughout the region. NASA satellites captured Igor's northern march toward the Labrador Sea yesterday.

NASA's Terra and Aqua satellites captured visible and infrared images of Hurricane Igor yesterday as he brought heavy rainfall into northeastern Canada. A visible image of Hurricane Igor over Newfoundland, Canada was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on NASA's Terra satellite on Sept. 21 at 14:15 UTC (10:15 a.m. EDT). At that time, Igor had re-strengthened and an eye appeared on the visible imagery.

One and a half hours later, at 1553 UTC (11:53 a.m. EDT), NASA's Aqua satellite captured an infrared image of Hurricane Igor's cold thunderstorms that extended from Labrador, Canada eastward over southern Greenland. Igor was moving northward toward into the Labrador Sea toward Labrador and Baffin Island.

At 5 p.m. EDT on Sept. 21, Igor completed its post-tropical transition and its core went from a warm core, tropical system to a cold core system. At that time, he was 125 miles north-northeast of St. Johns, Newfoundland, Canada near 49.3 North and 51.7 West. Igor still had sustained hurricane-force winds of 80 mph although they are expected to weaken today, Sept. 22. Igor's minimum central pressure was 950 millibars, and he was moving north-northeast near a super-speedy 39 mph!

As Igor moved north his circulation continued increase. By 5 p.m. EDT on Sept. 21, tropical-storm force winds extended outward up to 520 miles from its center making the system over 1,000 miles wide!

Environment Canada noted that Hurricane Igor passed just south and east of Newfoundland on Tuesday, Sept. 21 and brought heavy rain and strong winds. Heavy rainfall extended far north and west of Igor's center as it neared Newfoundland, and hurricane-force winds were reported even into the evening.

A trough of low pressure (an elongated area of low pressure) that had passed over Newfoundland the day before (Monday) Igor arrived was still in the vicinity and interacted with the hurricane. The trough took moisture and energy from Igor and caused more heavy rainfall over the region. There were reports of extensive flooding, power outages and wind damage throughout the eastern half of Newfoundland over the last two days. Igor is one storm that the Atlantic will not miss.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
