Field Project Experience

·         1993 Dec., Radar Operator and Microphysics Scientist on a NOAA P3 research aircraft (16 flight hours), Coastal Observations And Simulations with Topography(COAST I)

·         1995 Dec., Radar/Microphysics Scientist on a NOAA P3 research aircraft (50 flight hours) and planning/designing of the flight modules (see Fig. 2 of Bond et al. 1997), Coastal Observations And Simulations with Topography (COAST II)

COAST Project during the Postdoctoral Research

My postdoctoral research was mainly working on the numerical simulation of the 1 December 1995 storm during the COAST field experiment using the PSU/NCAR MM5 model. Below is an example of the MM5 simulation result using Vis5D graphic software. Isosurface in the foreground is the rain water field (qnw=0.25 g/kg), white arrow is for the wind vector at z=0.57 km level, and the vertical color slice in the background (roughly along the 48.3 N latitude) is the cloud ice field (blue color is for zero cloud-ice field). The perspective view is looking toward north with the Oregon and California coastal mountains on the right and the Pacific Ocean on the left.

The figure above shows clearly multiple rainbands intercepting the coastal mountains. Low-level wind is mostly southerly to southwesterly ahead of the leading principal rainband, and wind veers to westerly behind the rainband. The main objective of the COAST project is to advance our understanding of the complex interaction between storm precipitation and coastal topography.
