My graduate research goals include better
understanding how rainfall in the regions of Florida and the
Caribbean is changing as a result of climate change. For my
graduate thesis/dissection, in order to accomplish these
goals, among other tasks, I plan to compare and contrast
current climate and future climate high-resolution
simulations from the North American Regional Climate Change
Assessment Program (NARCAPP) and several other entities. We
also plan to compare the simulations of current climate
against different observational rain-gauge-based high
resolution data sets developed by the South Florida Water
Management District (SFWMD), the National Oceanic and
Atmospheric Administration (NOAA) and the NOAA Climate
Prediction Center (CPC), the University of Miami /
Rosenstiel School of Marine and Atmospheric Science (RSMAS),
and others. Furthermore, we plan to also evaluate and use
precipitation estimates from satellites from sources such as
the Tropical Rainfall Measuring Mission (TRMM) for looking
at rainfall over the oceans and over land. Eventually, using
the observations and model simulations, our plans are that a
statistical downscaling model will be developed, trained,
tested, and used to better forecast possible future rainfall
changes in our regions of interest. Finally, the
Ocean–Land–Atmosphere Model (OLAM), a new numerical
simulation model that is partly based on the Regional
Atmospheric Modeling System (RAMS), will be run,
tested/verified, and used. OLAM is a global model currently
being developed by Dr. Robert L. Walko, but it can be made
to run at very high spatial resolutions at any particular
region of interest.
