Linking Weather And Climate

Western Boundary Currents

gulfstream Western boundary currents play an important role in transporting heat poleward. Without the Gulf Stream (the western boundary current in the North Atlantic Ocean) parts of Europe would be much colder. Each western boundary current is part of a larger ocean gyre but the western boundary is intense compared to that on east.

    Western Boundary currents:
  • North Atlantic Gulf Stream
  • North Pacific Kuroshio
  • South Atlantic Brazil Current
  • South Pacific East Australian Current
  • South Indian Agulhas Current

To understand these ocean gyres we can use a simple model created by Henry Stommel. The Stommel model predicts the intensification of the jet along the western boundary and separation of jet at the latitude of zero wind stress curl (ZWCL). From there, we will look at some results from more complex models to see why the Gulf stream does not separate from land at the ZWCL. Read more


Research Interests

My primary research interest is in numerical modeling of weather and climate. Fortunately for me, there is no lack of research topics in this field; there is always room for improvement! In high school, my dream job was to be a computer programmer, not a glamorous video game programmer but a weather model programmer. I earned B.S. degree in Computer Science at Louisiana State University in 2006. Currently, I am enrolled in the Meteorology graduate program at Florida State University. Since my early dreams of weather modeling, I have taken an interest in climate modeling. This was in part from learning about the Charney-Shukla hypothesis, which explains the differences between predicting weather and climate (if I get around to it, there will be more details on this soon.)

I know that there is a lot of emphasis on model predictions for climate change in the media. My research is focused more on, but not limited to, seasonal climate prediction. Accurate seasonal forecasts have the potential to help us mitigate disasters and are much easier to verify than climate change.


Current Research

Using CCSM4 as a 9-month seasonal forecast tool.


Research Topics

El Niño/Southern Oscillation Fidelity in two coupled climate models or GCMs (general circulation models). One of these models is CCSM3.0, one of the models used in IPCC's AR4, and the other is a similar model with HYCOM ocean model replacing the POP ocean model of CCSM3.0.

Surface temperature trends in the South East United States. Anthropogenic land use plays a role in the temperature of the boundary layer (the well-mixed layer of air near the land surface). Compare daily minimum and maximum temperature trends in the South East to urbanization or irrigation.
