Mesoscale equatorial wind prediction in Southeast Asia during a haze episode of 2005

摘要: Even today fires are still utilized by local farmers in Southeast Asia to clear land. Air pollutants produced from the biomass burning activities Sumatera, for example, advected towards western coast of Peninsular Malaysia during southwest monsoon and can cause adverse effects on health population. This study TAPM (The Pollution Model) predict low level mesoscale characteristics an equatorial environment that encompassed island Sumatera period August 2005, when persistent haze was prevalent. able generate existence daily land sea breeze conditions near with relative success a moderately high Index Agreement 0.87 0.60 zonal meridional wind components, respectively, even without assimilation conditions. Strong southwesterlies were generated daytime over Straits Malacca associated breeze, while weak southeasterlies simulated 1900 time midnight The vertical profile within lowest kilometer atmosphere showed present mid-morning sunset, which interspersed stronger generally occurred above height 400 m. meteorological parameters such as speed, temperature, humidity successfully model comparatively correlation coefficients, RMSEs indices agreement observed values. turbulent kinetic energy profiles presence suppression at below 600 m coincided intense elevated levels pollution Malaysia.
