On Tuesday morning at 9:00 UTC (5:00 a.m. EDT) April 22, 2008, Rosie was located near 11.6 degrees south latitude and 105.8 degrees east longitude, or 815 nautical miles northwest of Learmonth, Australia. Rosie was moving southeast at 10 knots.

The image above was made from data captured by the Tropical Rainfall Measuring Mission (TRMM) satellite on Apr. 21 at 8:40 UTC (4:40 a.m. EDT). This TRMM image shows the horizontal pattern of rain intensity within Rosie. The center is located near the yellow, green and red areas, which indicate rainfall between 20 and 40 millimeters (.78 to 1.57 inches) per hour. The red area is considered moderate rainfall.

Hurricane Season 2008: Tropical Storm Nargis (Indian Ocean)
04.30.08

April 30, 2008

Cyclone Signals Start of Season in North Indian Ocean

The recent formation of Tropical Cyclone Nargis in the Bay of Bengal coincides with the start of cyclone season in the North Indian Ocean, which typically runs from April through December. Despite the long season, the region, which includes the Bay of Bengal and the Arabian Sea, on average has just over 5 named storms per year with 2 becoming full tropical cyclones. Last year there were two storms, both of which were notable. In June, Gonu, an extremely rare Category 5 cyclone in the Arabian Sea, became the strongest storm ever recorded in that part of the basin. Despite weakening before landfall, it went on to kill 72 people in the area as a result of flooding. In November, a slightly less powerful but far more deadly storm struck the southern coast of Bangladesh in the Bay of Bengal. The region, which is known for it's high death tolls, suffered over 3400 fatalities. As a result, Cyclone Nargis is being closely watched.

Nargis formed into a tropical cyclone on the 27th of April 2008 in the central Bay of Bengal about 360 miles off of the southeast coast of India. Initial movement remained northwesterly. The Tropical Rainfall Measuring Mission satellite (known as TRMM) was placed into service in November of 1997. From its low-earth orbit, TRMM can provide valuable images and information on tropical cyclones around the Tropics using a combination of passive microwave and active radar sensors.

The first image shows Nargis just as it was becoming a tropical storm. The image was taken at 04:37 UTC (10:07 am local time) 27 April 2008 and shows the horizontal pattern of rain intensity within the storm. Rain rates in the center swath are from the TRMM Precipitation Radar (PR), the first precipitation radar in space, while rain rates in the outer swath are from the TRMM Microwave Imager (TMI). The rain rates are overlaid on infrared (IR) data from the TRMM Visible Infrared Scanner (VIRS). At this stage the center is not yet very well defined, although a fledgling circulation is evident by the slight curvature in the rain bands. At the time of this image, the estimated sustained winds had not yet reached 35 knots (40 mph), the minimum threshold for tropical storm intensity. Nargis officially became a tropical storm less then 8 hours after this image was taken.

Over the next day and a half, the system continued to steadily strengthen, becoming a Category 1 cyclone during the day on the 28th and a Category 2 cyclone later that night.


The next image from TRMM was taken at 18:32 UTC 28 April (12:02 am 29 April local time) and shows a much different looking storm. A large, well-defined eye is now readily apparent. In the western semi-circle, a strong eye-wall can be identified by intense rainfall (dark red arc). The storm is very symmetric with rain bands now tightly curving around the center (green rings indicating moderate intensity rain). At the time of this image, Nargis was a Category 1 storm with maximum sustained winds estimated at 75 knots (86 mph) by the Joint Typhoon Warning Center. The system was upgraded to a Category 2 storm with sustained winds of 85 knots (98 mph) few hours later.

This last image was taken simultaneously with the previous and shows a 3D picture of Nargis courtesy of the TRMM PR. A half ring of tall towers (highlighted in red) reveals areas of deep convection (e.g., thunderstorms) that are associated with the intense rainfall in the western eyewall that was seen in the previous image. These tall towers can be a sign of future intensification as they release substantial amounts of heat into the core of the storm. At present, Nargis has begun to recurve towards the east-northeast and has weakened slightly. However, some intensification is forecast before the system makes an expected landfall along the western coast of Myanmar (Burma).

TRMM is a joint mission between NASA and the Japanese space agency JAXA.

Cyclone Nargis Poised to Strike the Myanmar Coast

> Click for larger image Cyclone Nargis is a Category two hurricane, and is forecast to strike Myanmar coast West of Yangon.

At 9:00 GMT (5:00 a.m. EDT) on Tuesday, April 29, 2008, Nargis was packing sustained winds of 85 knots (97 mph) with higher gusts. It was located near 13.6 degrees south latitude and 85.2 degrees east longitude, or 565 miles south-southwest of Calcutta, India. Nargis was moving north at 4 knots (4 mph).

Threatened landmasses include: India, Andaman and Nicobar Islands, Myanmar, Bangladesh. Forecasters expect Nargis will turn to the northeast and will continue to intensify. It is generating wave heights to 24 feet, and heavy thunderstorms are expected over the Andaman and Nicobar Islands. Squally winds are also forecast along the coasts of Andhra Pradesh and Tamil Nadu fishermen are advised not to venture out to sea.

This infrared image of Nargis was created on April 29 at 7:47 UTC (3:47 a.m. EDT) by data from the Atmospheric Infrared Sounder (AIRS), an instrument that flies aboard NASA's Aqua satellite.

This AIRS image shows the temperature of the cloud tops or the surface of the Earth in cloud-free regions. The lowest temperatures (in purple) are associated with high, cold cloud tops that make up the top of Nargis (shown as the circular purple area on this satellite image). The infrared signal of the AIRS instrument does not penetrate through clouds. Where there are no clouds the AIRS instrument reads the infrared signal from the surface of the Earth, revealing warmer temperatures (red).

berita ini mohon dibaca..ini serius!! save our planet!!

ooi mbak maksudmu apaan sih, wa ribet baca bahasa Inggrisnya....


lagipula kayaknya kurang pas ditaro di bagian school deh

kalo ngga request forum aja ama kanmuri, forum khusus buat ngomongin sesuatu yang umum kayak gini... ini cuma pemberitahuan aja 'kan??

atau kyo pindahin aja dulu ke tempat yang tepat...

dasar emang isei nih calon istri pak afcar...doyan sains..... mana bahasa inggris lage.......

maaf.maksud aku buat thread ini karena ada 'malaikat' yang terus mendesak wa buat bikin thread ini...jadinya wa gak sempat nerjemahin..itu tadi cuma pembukaan doang...hehehehe...jumlah yang meninggal adalah sebanyak 4000 jiwa dan 3000 jiwa yang lainnya masih menghilang..terletak di yangon,myanmar.

@ao n kyou : keliatanya taro disini aja dhe^^;;

wew.... emg.. bener2.... ga sempet baca ampe akhir sih.. *males* btw, to the pointnya apa ?

@moy : as you wish ^^


yup, issei to the pointnya paan?? (capek nyari kamus)

intinya..gimana caranya supaya disaster gak terjadi di bumi ini

ya lakukan kayak gerakan stop global warming gitu kan??? yg menghemat listrik, dan bahan bumi dll... gitu deh klo ga salah

@ kyo : kupikir juga begitu..tapi kayaknya itu bukan point yang tepat dah.

iya juga sih... yaaah kalao emang takdirnya bumi harus hancur..kita pasrah saja.. tapi sebelum pasrah ya usaha dulu lah..

here the news..

When Superstorm Plasmas and Earth's Magnetosphere Collide
05.29.08

> Other images (pdf) A hotbed of activity, the sun is capable of making giant superstorms. When it does, the storms release plasma into the solar wind.

Large solar flares often blast material from the sun’s outer atmosphere, called the corona. These coronal mass ejections (CMEs) can spew billions of tons of plasma away from the sun and toward Earth at speeds faster than 1.5 million mph.

When plasma from a superstorm collides with Earth’s magnetosphere, the region surrounding Earth dominated by its magnetic field, the effects are felt here on Earth.

As plasma from a superstorm interacts with Earth’s magnetosphere, it can trigger spectacular displays of the Northern Lights, called auroras, interfere with communications between satellites and airplanes traveling near the North Pole, and interrupt global positioning systems and our power grid.

NASA scientists have uncovered new details about how plasma from superstorms interacts with Earth’s magnetosphere. Mei-Ching Fok, an astrophysicist at NASA’s Goddard Space Flight Center in Greenbelt, Md., and her team have created a computer model that evaluates contributions to magnetospheric pressure from the solar wind, polar wind, auroral wind, and plasmaspheric wind.

Their simulation of sources of superstorm plasmas found that energetic protons from the plasmasphere, a donut-shaped region of the inner magnetosphere, dominate the magnetosphere’s pressure during a superstorm’s main phase. Until now, scientists thought energetic protons from the solar wind most affected the magnetosphere.

“The surprising result of this model is that the magnetosphere’s main phase pressure [the magnetosphere’s pressure during a superstorm’s main phase] is dominated by energetic protons from the plasmasphere, rather than from the solar wind,” says Fok. She and her team will present their findings on May 29 at the American Geophysical Union conference in Ft. Lauderdale, Fl.

During space storms, the plasmasphere is squashed and pressurized by the solar wind, forming a long tail called the plasmaspheric plume. The plume particles are picked up and further energized by the solar wind. When they re-enter the magnetosphere, they supply the majority of energetic protons that affect the magnetosphere’s main phase pressure during a superstorm event.

Simulating the sources of superstorm plasmas will help scientists better understand superstorms and paves the way to predicting their impact on Earth. The details uncovered in the team’s model provide a new piece of the Sun-Earth puzzle.
