Sediments from Batang Lupar River, Malaysia

1.2N 111.4E

Indonesia and Malaysia - June 21st, 2011

Several rivers can be observed emptying tan sediments into the South China Sea near off the coast of Malaysia, near the border with Indonesia.

The widest of those visible here is the Batang Lupar River. It is famous for its tidal bore, which comes in from the river mouth and fills up the river very rapidly in the course of about 10 minutes. The wave crest at Sri Aman is up to 2 to 3 metres high.

 

Sediments in Qiongzhou Strait by Leizhou Peninsula and Hainan Island, China

China - June 10th, 2011

Sediments surround the Leizhou Peninsula (above) and are present in the Qiongzhou Strait and some of the coastline of Hainan Island (below).

The strait, also called the Hainan Strait, separates the Leizhou Peninsula in Guangdong, southern China, from Hainan Island.

It also connects the Gulf of Tonkin in the west to the James Shoal on the eastern edge of the South China Sea. The strait has an average width of 30 km and a maximum water depth of approximately 120 m.

 

Typhoon Megi (15W) Expected to Intensity and Make Landfall Over Luzon – October 16th, 2010

Typhoon Megi (15W) - October 15th, 2010

Enhanced image

Track of TY 15W

Typhoon Megi (15W) is located approximately 780 nm east of Manila, Philippines, and has tracked northwestward at 15 knots over the past six hours. Maximum significant wave height is 27 feet.

Animated infrared (IR) satellite imagery and an AMSU microwave image depict a well-defined low level circulation center (LLCC) with tightly-curved banding.

Animated water vapor imagery continues to indicate good overall outflow with some improvement along the northwest quadrant as the tutt low, previously located near 20N 130E, begins to fill and move northwestward.

The current intensity of 95 knots is slightly higher then Dvorak estimates of 90 knots from PGTW and RJTD based on an improved banding signature in IR imagery over the past 6 hours.

TY 15W is currently tracking northwestward along the southwestern periphery of the mid-level subtropical ridge (STR) toward a weakness associated with a major mid-latitude shortwave trough. As the trough continues to propagate northeastward, the STR is expected to reorient and re-build to the west, allowing the system to turn westward between TAU 24 and TAU 36.

Megi is forecast to continue to intensify under favorable upper level and oceanic (high SST and high ocean heat content) conditions as it approaches Luzon. The system is expected to make landfall over northern Luzon between TAU 48 and TAU 72 at or near super typhoon intensity and should weaken considerably due to interaction with the mountainous terrain of Luzon. After TAU 72, Megi is expected to re-emerge into the south China Sea at typhoon intensity and track westward toward Hainan.

Cloud Streets and Hazy Skies by Hainan Island, China

China - March 5th, 2010

Hainan Island (Hainan Dao) comprises all but three percent of the land mass of Hainan Province, China, despite the fact that the province includes some two hundred islands scattered among three archipelagos off the southern coast.

Hainan Island is located in the South China Sea, separated from Guangdong’s Leizhou Peninsula to the north by a shallow and narrow strait. To the west of Hainan is the Gulf of Tonkin. Hainan Dao has an area of 33,920 square kilometers and is China’s southernmost and smallest province. Wuzhi Mountain (1,876 m) is the highest point on the island.

Much of the land and water visible here appear hazy due to smoke from hundreds of fires blazing across Southeast Asia at the time the image was taken. Some clouds hug the southern coast of the island and reach across the sea in parallel rows, a phenomenon known as cloud streets.

Vegetation Index and Deforestation in the Philippines

7.8N 124.8E

Philippines - March 5th, 2010

Philippines - March 5th, 2010

The Philippines is an archipelago of 7,107 islands bordering the Philippine Sea on the east, the South China Sea on the west, and the Celebes Sea on the south. Most of the mountainous islands are covered in tropical rainforest and volcanic in origin.

Although most the islands visible in this FAPAR image shows a good to high vegetation index (green to dark red), deforestation, often the result of illegal logging, is an acute problem in the Philippines. Forest cover declined from 70% of the country’s total land area in 1900 to about 18.3% in 1999.

Many species are endangered and scientists say that South East Asia, which the Philippines is part of, faces a catastrophic extinction rate of 20% by the end of the century.
