I am working within the Center for Science in the Earth System at JISAO to develop techniques for simulating the regional climate in support of applications research within the Climate Impacts Group.
Simulations of global climate change and variabilty are critical to formulating quantitative adaptation stategies to respond to changes in the local climate. Global models, however, represent atmospheric and surface parameters at a horizontal resolution of approximately 300 km. This resolution is much to coarse for simulating regional processes such as precipitations and streamflows that determine the effects of climate on regional systems. Furthermore, global models do not account for surface features, such as topography and land use, that determine much of the significant climate features at regional scales.
We use two techniques to downscale global climate simulations:
Other research interests of mine include upper-tropospheric moisture and its relationship to the climate. Most of my work in this field has been in using satellite remote sensing data to understand various aspects of this problem. I have an ongoing interest in understanding the transport of moisture into the subtropics using satellite data, conventional meteorological data, and atmospheric model results.
At the Climate and Radiation Branch at the Goddard Space Flight Center, I used TOVS radiance observations to examine the moisture distribution in general circulation models.
While in the Geology and Geophysics Department at Yale University, I examined the accuracy of satellite observations, in situ moisure measurements, and radiative transfer calculations using simulaneous aircraft and GOES satellite observations.
