ESSO - Indian National Centre for Ocean Information Services

ABOUT THE TALK:

Predicting intensity changes, including, in particular, rapid intensity changes, in tropical cyclones (TCs) is a complex and challenging multiscale problem. To motivate the improvement of intensity forecasts, NOAA created the Hurricane Forecast Improvement Program (HFIP) in 2009. Supported by HFIP, noticeable progress has been made to improve the prediction of TC intensity changes by upgrading numerical models, advancing data assimilation techniques, expanding the observations assimilated into numerical models, and, above all, investing in basic research to better understand TC intensification. The state-of-the-art HWRF model is used to explore processes that have been shown to be important to TC intensification. A brief review of the existing axisymmetric theory for the intensification of TCs is also provided. However, TCs are rarely axisymmetric. The asymmetric structure in the inner core of a TC may be generated by both internal dynamics and external forcing due to environmental factors such as wind shear and moisture.

ABOUT THE SPEAKER:

Dr. Sundararaman Gopalakrishnan is a senior meteorologist with the U.S. National Oceanic and Atmospheric Administration (NOAA)’s Atlantic Oceanographic and Meteorological Laboratory (AOML)’s Hurricane Research Division (HRD) and principal architect of NOAA’s Hurricane Weather Research and Forecasting (HWRF) system. His research involves simulating a variety of complex, non-linear, scale interacting systems starting from dry thermals (Large Eddy Simulations) to hurricanes; examining the mesoscale structures and evolution as well as the mechanism(s) whereby they develop; testing theories, hypotheses and various near-surface model physical representations; and finally interpreting, to the extent possible, the modeled and the observed behavior of these systems.
