Fires in Southeast Asia
The climate of Southeast Asia is controlled by the monsoon, a climate characterized by two seasons: a wet phase, where winds blow inland from over the ocean, bringing frequent rains; and a dry phase, where winds blow from the continent out to sea. In April, the dry phase of the monsoon is drawing to a close, and agricultural burning has been underway for several months, as farmers prepare their fields and pastures for the upcoming growing season.
In 2005, Southeast Asias annual dry season was being magnified by an intense drought. On April 10, 2005, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASAs Aqua satellite captured this scene of intense burning in Myanmar, Thailand, northern Laos, Vietnam and China. The number of actively burning fires (marked in red) is particularly high in northern Laos. Thick, brownish-gray smoke spreads eastward from the fires.

Regional Fire Weather
The Regional South East Asia Fire Danger Rating System (SEA FDRS) is a joint effort between the Canadian Forest Service (CFS) and the Malaysian Meteorological Service (MMS), supported by the Canadian International Development Agency (CIDA). Daily updated SEA Fire Danger Rating can be downloaded on the following website of MMS, and background information on the project can be found at the SEA FDRS Project website.
Latest example of a SEA FDRS product:
The Fire Weather Index (FWI) values shown on the map are numerical ratings offire intensity.
Information from the Initial Spread Index (ISI) and Build Up Index (BUI) iscombined to provide a numerical rating of fire intensity.
This index is used to indicate the difficulty of fire control based on the headfire intensity and fire fighting capability.
Information on the Indonesian Fire Danger Rating System (Indonesian FDRS) is provided by the Indonesian Bureau of Meteorology and Geophysics (BMG) in Jakarta. The site provides information for fire managers working to prevent and control vegetation fires and smoke in Indonesia.
