NASA sees birth of Atlantic's subtropical depression seven: Bermuda on watch

NASA sees birth of Atlantic's subtropical depression seven: Bermuda on watch
2014-10-10
(Press-News.org) The seventh depression of the Atlantic Ocean Hurricane Season was born on Oct. 10, but it's subtropical. NASA's Aqua satellite looked at the developing depression in infrared light and saw strong thunderstorms within.

The Atmospheric Infrared Sounder or AIRS instrument aboard NASA's Aqua satellite captured data on developing Subtropical Depression 7 on Oct. 10 at 05:41 UTC (1:41 a.m. EDT). AIRS identified several areas of strong thunderstorms around the developing center of circulation. Some of those thunderstorms were high in the troposphere with cloud top temperatures near -63F/-53C and had the potential for dropping heavy rainfall. The circulation continued to organize after Aqua passed by and a depression formed.

A Tropical Storm Watch was posted at 11 a.m. EDT on Oct. 10 for Bermuda. The National Hurricane Center noted that tropical storm conditions are possible on Bermuda late Saturday, Oct. 11 or on Sunday, Oct. 12.

A subtropical cyclone, which is what this depression is, is different from a tropical depression. Here's how the National Hurricane Center distinguishes subtropical from tropical: A subtropical cyclone, like Subtropical Depression 7, "is a non-frontal low-pressure system that has characteristics of both tropical and extra-tropical cyclones. Like tropical cyclones, they are non-frontal, synoptic or large-scale cyclones that originate over tropical or subtropical waters, and have a closed surface wind circulation about a well-defined center. In addition, they have organized moderate to deep convection (development of clouds and thunderstorms from rising air), but lack a central dense overcast. Unlike tropical cyclones, subtropical cyclones derive a significant proportion of their energy from baroclinic sources, and are generally cold-core in the upper troposphere, often being associated with an upper-level elongated low pressure area or trough. In comparison to tropical cyclones, these systems generally have a radius of maximum winds occurring relatively far from the center (usually greater than 60 nautical miles), and generally have a less rounded (symmetric) wind field and distribution of convection."

At 11 a.m. EDT the center of subtropical depression Seven was located near latitude 23.8 north and longitude 63.7 west. That puts the center of Subtropical Depression 7 about 590 miles (950 km) south of Bermuda. Maximum sustained winds are near 35 mph (55 kph) with higher gusts. Some strengthening is forecast and the depression is forecast to become a subtropical storm later today.

Subtropical Depression 7's estimated minimum central pressure is 1005 millibars. The depression is moving toward the northwest near 10 mph (17 kph). A gradual turn toward the north, followed by a turn toward the northeast on Sunday.

Getting sharp images from dull detectors
2014-10-10
Observing the quantum behavior of light is a big part of Alan Migdall's research at the Joint Quantum Institute. Many of his experiments depend on observing light in the form of photons---the particle complement of light waves---and sometimes only one photon at a time, using "smart" detectors that can count the number of individual photons in a pulse. Furthermore, to observe quantum effects, it is normally necessary to use a beam of coherent light, light for which knowing the phase or intensity for one part of the beam allows you to know things about distant parts of ...

BIDMC researchers looks at impact of patient-to-physician messaging

2014-10-10
BOSTON – Email has become one of the most widespread forms of communication, with its streamlined interactions benefiting both businesses and individuals. With the advent of secure patient web portals and the faith that online access has the potential to improve care, the medical industry is slowly catching up. And while it may take time before it's known what impact email exchanges might have on patients and their care, a new study from Beth Israel Deaconess Medical Center (BIDMC) offers some early insights into the effects on doctors, suggesting that reimbursement ...

NASA gathering data on Super Typhoon Vongfong as Japan prepares
2014-10-10
Super Typhoon Vongfong continued on its trek north through the Philippine Sea while slightly weakening on Oct. 10. NASA's TRMM and Aqua satellites provided forecasters with cloud extent, rainfall rates and distribution and more. Vongfong was a super typhoon with wind maximum sustained winds of 145 knots (167 mph) when the TRMM satellite flew over on October 8, 2014 at 2328 UTC 7:28 p.m. EDT). TRMM's Microwave Imager showed that Vongfong was producing rainfall over a large area and heavy rainfall in the eye wall (the powerful thunderstorms around the open eye) and in multiple ...

No single explanation for biodiversity in Madagascar

No single explanation for biodiversity in Madagascar
2014-10-10
DURHAM, N.C. –- No single "one-size-fits-all" model can explain how biodiversity hotspots come to be, finds a study of more than 700 species of reptiles and amphibians on the African island of Madagascar. By analyzing the geographic distribution of Madagascar's lizards, snakes, frogs and tortoises, an international team of researchers has found that each group responded differently to environmental fluctuations on the island over time. The results are important because they suggest that climate change and land use in Madagascar will have varying effects on different ...

NASA sees intensifying Tropical Cyclone Hudhud headed for landfall in India
2014-10-10
NASA's Aqua satellite passed over Tropical Cyclone Hudhud on Oct. 10 as it reached hurricane-force. The Atmospheric Infrared Sounder or AIRS instrument that flies aboard NASA's Aqua satellite read temperatures of thunderstorm cloudtops that make up Tropical Cyclone Hudhud when it passed overhead on Oct. 9 at 19:53 UTC (3:53 p.m. EDT). The data showed the coldest cloud top temperatures were in thunderstorms circling a developing eye. Cloud top temperatures were as cold as -63F/-53C, which have the potential for dropping heavy rainfall. Hudhud's maximum sustained winds ...

Interactive history beats interactive chat for website engagement

2014-10-10
Small cues that display a user's transaction history may help a website feel almost as interactive as chatting with an online customer service agent, paving the way for more cost-effective websites, according to researchers. "One of the challenges with online interactivity is trying to imbue the site with a sense of contingency -- the back-and-forth feel of a real conversation," said S. Shyam Sundar, Distinguished Professor of Communications and co-director of the Media Effects Research Laboratory. "What we found is that providing some information about a user's interaction ...

Tiny travellers of the animal world: Hitchhikers on marine driftwood

Tiny travellers of the animal world: Hitchhikers on marine driftwood
2014-10-10
A new study led by a Canadian marine zoologist reviews the world list of specialist driftwood talitrids, which so far comprises a total of 7 representatives, including two newly described species. These tiny animals with peculiar habits all live in and feed on decomposing marine driftwood. Dispersed across distant oceanic islands they use floating driftwood to hitch a ride to their destination. The study was published in the open access journal Zoosystematics and Evolution. Tourists are familiar with talitrids as sandhoppers, found in burrows on sand beaches, or shorehoppers, ...

Antiretroviral therapy benefits HIV-infected stimulant users, UCSF study shows

2014-10-10
New clinical research from UC San Francisco shows that 341 HIV-infected men who reported using stimulants such as methamphetamine or cocaine derived life-saving benefits from being on antiretroviral therapy that were comparable to those of HIV-infected men who do not use stimulants. That said, those who reported using stimulants at more than half of at least two study visits did have modestly increased chances of progressing to AIDS or dying after starting antiretroviral therapy compared to non-users. The data was collected between 1996 and 2012. "Patients with HIV ...

Pneumococcal vaccine reduces antibiotic-resistant infections in children by 62 percent

2014-10-10
PHILADELPHIA –The pneumococcal vaccine recommended for young children not only prevents illness and death, but also has dramatically reduced severe antibiotic-resistant infections, suggests nationwide research being presented at IDWeek 2014™. Pneumococcal infection – which can cause everything from ear infections to pneumonia and meningitis – is the most common vaccine-preventable bacterial cause of death. The 13-valent pneumococcal conjugate vaccine (PCV13), first available in 2010 (replacing 7-valent pneumococcal conjugate vaccine, PCV7), reduced the ...

Real-life social networking prompts people to get tested for HIV

2014-10-10
PHILADELPHIA – Old-school face-to-face social networking is a more effective way to identify people with HIV than the traditional referral method, suggests research being presented at IDWeek 2014™. The study shows that social networking strategies (SNS) – enlisting people in high-risk groups to recruit their peers to get tested – is more efficient and targeted than traditional testing and referral programs, resulting in 2-1/2 times more positive test results. As many as 20 percent of HIV-positive people are unaware of being infected with the virus, ...
