NASA sees the start of India's monsoon season
2015-06-09
(Press-News.org) Monsoon rainfall, although a little later than normal, started on June 5, 2015, in southern India. The Global Precipitation Measurement (GPM) core satellite gathered rainfall data that was used to create an animation that shows where the precipitation fell as the season started.
Due to El Nino conditions some meteorologists predict that monsoon rainfall will be below normal this year. Cooling rainfall comes to the country after high temperatures preceding the monsoon have caused the reported deaths of more than 2,300 people.
Data from the NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG) was used to create an image and animation to show the advent of India's monsoon.
Rainfall data is captured by the Global Precipitation Measurement (GPM) satellite mission. GPM orbits in space to observe precipitation around the world. A snapshot of the precipitation is taken every 30 minutes, then processed and made available to users 18 hours later. New rain maps are routinely created by programs that merge the data from the GPM Core Observatory, a joint mission of NASA and the Japan Aerospace Exploration Agency (JAXA), and a dozen other weather satellites. These maps, called Integrated Multi-satellite Retrievals for GPM (IMERG), are false-colored with rain in greens and reds, and snowfall depicted in blues and purples.
Rainfall estimates for the week of June 1 through 8, 2015, showed that some heavy showers have dropped over 120 millimeters (4.7 inches) of rain in the few days before June 8.
The analysis also indicates that the country of Nepal, which was recently hit by devastating earthquakes, was having some heavy rainfall preceding the monsoon in that area.

The remnants of former Hurricane Blanca are blanking out over the northern part of Mexico's Baja California today, June 9. NOAA's GOES-West satellite captured an infrared image of Blanca's remnants revealing a disorganized storm. All watches and warnings have been dropped.
NOAA's GOES-West satellite took an image of Blanca's remnants as it continued moving over the northern Baja California peninsula on June 9 at 1245 UTC (8:45 a.m. EDT). The clouds associated with the remnants were over the northern Baja and over the northern portion of mainland Mexico. The western-most ...

WASHINGTON, DC, June 9, 2015 - If you want to assign blame on an overcast day, then cast your eyes on the tropics. Water vapor originating from the Earth's tropics is transported to midlatitudes on long filaments of flowing air that intermittently travel across the world's oceans. When these airy tendrils make landfall, they can cause severe floods and other extreme weather events. Yet despite the importance of these "atmospheric rivers" for the global water and heat cycles, the mechanism behind their formation is still a mystery.
But a new study, published this week ...

Between 1993 and 2012, the incidence rate of acute traumatic spinal cord injury remained relatively stable in the U.S., although there was an increase among older adults, mostly associated with an increase in falls, according to a study in the June 9 issue of JAMA, a theme issue on the Americans with Disabilities Act.
Traumatic spinal cord injury leads to chronic impairment and disability. Despite the substantial effects of this injury on health-related quality of life and health care spending, contemporary data on trends in incidence, causes, and medical care are limited, ...

A control system that incorporated electrical signals generated during muscle contractions and gait information resulted in improved real-time control of a powered prosthetic leg for different modes of walking (such as on level ground or descending stairs), according to a study in the June 9 issue of JAMA, a theme issue on the Americans with Disabilities Act.
Most prosthetic lower limbs are mechanically passive (cannot provide power) and so do not restore full function. Leg prostheses that provide power are becoming available; however, different ambulation modes require ...

Among applicants to U.S. medical schools, those with disabilities who obtained extra test administration time for the Medical College Admission Test in use from 1991 to January 2015 had no significant difference in rate of medical school admission but had lower rates of passing the United States Medical Licensing Examination Step examinations and of medical school graduation, according to a study in the June 9 issue of JAMA, a theme issue on the Americans with Disabilities Act.
Individuals with documented mental and physical disabilities may receive testing accommodations ...

Following implementation of rotavirus vaccination in 2006, all-cause acute gastroenteritis hospitalization rates among U.S. children younger than 5 years of age declined by 31 percent - 55 percent in each of the post-vaccine years from 2008 through 2012, according to a study in the June 9 issue of JAMA.
Eyal Leshem, M.D., of the U.S. Centers for Disease Control and Prevention, Atlanta, and colleagues examined both all-cause gastroenteritis and rotavirus-related hospitalizations among children younger than 5 years from 2000 through 2012. The researchers analyzed State ...

Did the cross-country drive that you planned using an online mapping service take twice as long as expected?
In a new study published in the Articles in Advance section of Transportation Science, a journal of the Institute for Operations Research and the Management Sciences (INFORMS), Microsoft researchers working on a project for Bing Maps explain how they developed the first routing engine that satisfies a large number of algorithmic requirements that overcome barriers to generating directions on multi-stage trips like coast-to-coast drives.
Customizable Route Planning ...

Rochester, MN, June 9, 2015 - U.S. government-issued dietary recommendations continue to evolve over time. In a special article published in Mayo Clinic Proceedings, an obesity theorist and cardiovascular health researchers claim that the main source of dietary information used by the U.S. Government's 2015 Dietary Guidelines Advisory Committee (DGAC) is scientifically flawed because the underlying data are primarily informed by memory-based dietary assessment methods (M-BMs) (eg, interviews and surveys). In an editorial response nutrition experts suggest that the purported ...

Reacting positively to stressful situations may play a key role in long-term health, according to researchers.
In a study measuring adults' reactions to stress and how it affects their bodies, researchers found that adults who fail to maintain positive moods such as cheerfulness or calm when faced with the minor stressors of everyday life appear to have elevated levels of inflammation. Furthermore, women can be at heightened risk.
Inflammatory responses are part of the body's ability to protect itself via the immune system. However, chronic -- long-term -- inflammation ...

DARIEN, IL - A new study suggests that insomnia decreases empathy in health care workers and may lead to adverse clinical outcomes and medical errors.
Results show that subjects with an Insomnia Severity Index ISI of greater than 8, scored significantly higher across all four subscales of empathy.
"Insomnia affects empathy in health care workers which can lead to adverse clinical outcomes,"
said lead author Venkatesh Basappa Krishnamurthy, MD, assistant professor, Sleep Research and Treatment Center, department of psychiatry, Penn State College of Medicine in Hershey, ...
