Abstract

Atmospheric Boundary Layer (ABL) is the lowest part of the atmosphere where the flow field is directly affected by interaction with earth’s surface and sensitive to various condition at the surface. In a short period, ABL height could varied significantly  as a result of several factors, including large scale of atmospheric dynamics, cloudiness, convective mixing and diurnal variation of solar radiation. In Indonesia, studies related to ABL is still limited, so in this study aims to know the relation between ABL height and the weather condition using vertical wind profile from observation data (weather radar and radiosonde) and WRF-ARW model simulation. The result is though it has moderate correlation and high error towards the observation, WRF-ARW model simulation is able to determine the ABL height profile in different weather condition. Weather conditions could be affected by the height of ABL. In fair weather conditions, the ABL height is higher than the ABL height in cloudy or rainy weather conditions.
