Vegetation Index of Southeast Asia

11.0N 106.7E

May 4th, 2011 Category: Vegetation Index

Southeast Asia - April 27th, 2011

This FAPAR image shows the vegetation index of part of Southeast Asia, including areas of Vietnam, Cambodia and Thailand (right to left, above), as well as Malaysia (below) and Indonesia (bottom of full image).

Most of the image shows predominantly good (green) to high (rusty red) photosynthetic activity, particularly in Malaysia and on the Indonesian island of Sumatra. Some areas of low activity (yellow) can be observed in Cambodia near the Tonle Sap.

Vegetation Index of Malaysia and Sumatra, Indonesia

Indonesia - February 18th, 2011

This FAPAR image depicts the vegetation index of the Indonesian island of Sumatra (below) and Malaysia (above). The two are separated by the Strait of Malacca.

Both Sumatra and Malaysia show a mixed vegetation index ranging from good to high. Areas of good photosynthetic activity appear green, while those of high activity are rusty red in color.

Track of Area of Convection

An area of convection has persisted approximately 235 nm north-northwest of Kuala Lumpur, Malaysia. Animated infrared satellite imagery shows flaring convection, associated with a loosely organized low level circulation center (LLCC), persisting over the Malay Peninsula.

Over the past several hours, surface observations have indicated variable winds (10-15 knots) out of the west-northwest with a 24 hour pressure decrease of 6 mb’s.

Upper level analysis indicates broad upper level diffluence with low vertical wind shear (10 to 15 knots). Maximum sustained surface winds are estimated at 20 to 25 knots. Minimum sea level pressure is estimated to be near 1003 mb.

Due to persistent deep convection and favorable upper level conditions, the potential for the development of a significant tropical cyclone within the next 24 hours is fair.

Indonesian Island of Sumatra and Malay Peninsula in Southeast Asia

Malaysia - April 28th, 2010

This FAPAR image shows the Indonesian island of Sumatra (below) and part of Malaysia on the lower end of the Malay Peninsula, although the entire peninsula including parts of Thailand and Myanmar is visible after opening the full version.

Most of the land appears green to red, indicating good to high levels of photosynthetic activity. Only a few areas appear yellow, indicating a low vegetation index.

Sumatra supports a wide range of vegetation types which are home to a rich variety of species, including 17 endemic genera of plants. The island has lost 48% of its natural forest cover since 1985, however, and many of the remaining species are endangered.

Vegetation Index of Myanmar, Thailand and Malaysia

Thailand - March 5th, 2010

This FAPAR image focuses on the long peninsula in Southeast Asia that divides the Gulf of Thailand (right) from the Andaman Sea (left). The northern half of the peninsula is shared by Myanmar (west) and Thailand (east), while the southern half is part of Malaysia. Parts of Cambodia (center) and Vietnam (far right) are also visible in the upper part of the image, and part of Indonesia can be seen in the full image, south of Malaysia.

Most of the peninsula and land in Indonesia appear red to dark green, indicating high photosynthetic activity. Parts of Cambodia and Vietnam, however, appear yellow, an indication of low activity.
