Research Areas
1. Initiation and propagation of the Madden-Julian Oscillation (MJO).
- We use theory, observations, and high-resolution numerical simulations to understand the initiation and propagation mechanisms of the MJO. In particular, we use a tropical channel model (TCM) based on the WRF model to explore possible role of the extratropics on the MJO.
2. Role of topography and land-sea contrast in the Maritime Continent
- Role of topography and land-sea contrast on the tropical ISO is studied using idealized and real simulations. Of particular interest is the modulation of the diurnal cycle of precipitation by the topography.
3. Land-Air-Sea Interactions
- We are studying several overlooked processes associated with the land-air-sea interactions. For example, we are looking at the sensitivity of rainfall to resolution of topography data.
4. Urban climate
- We study the near surface conditions over urban areas and how these conditions are modified by local and non-local processes. We are now working on three urban areas, Houston, New York and Manila.
