I conduct research on regional climate change and climate impacts within the Climate Impacts Group at JISAO, with a primary focus on the US Pacific Northwest. The primary focus of my work is to transform global climate change simulations into information suitable for studying regional impacts of climate change.
Simulations of global climate change and variabilty are the foundation for our knowledge about the climate. Global models, however, represent atmospheric and surface parameters with much too coarse a horizontal resolution to simulate regional processes, such as precipitation and streamflow, that determine the effects of climate on the region. Furthermore, global models do not account for surface features, such as topography and land use, that determine the regional climate.
We have implemented two methods to develop high-resolution climate scenarios:
Regional climate data produced using these methods is used to support climate impacts applications as well as basic research into regional climate change.
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.
