  • July 5, 2017: Toward Skillful Subseasonal Prediction of North Atlantic Hurricanes
    Kun Gao (GFDL/Princeton University)
    Skillful prediction of hurricane activity on the subseasonal scale (from two weeks to less than a season) is important for reducing the hurricane damage in coastal regions. In this talk, I will present a synthetic summary of the recent efforts on the subseasonal prediction of North Atlantic hurricanes based on the non-hydrostatic two-way-nested version of GFDL HiRAM. Key results are 1) the HiRAM not only well captures the impact of Madden-Julian Oscillation (MJO) on global tropical cyclone genesis, but also faithfully reproduces the modulation of MJO on regional hurricane activity, especially in the Gulf of Mexico and Caribbean Sea region; 2) The two-way-nested grid with 8-km resolution realistically simulates the hurricane size distribution and inner-core structure, which leads to significant improvement in the subseasonal prediction of major hurricanes in North Atlantic.

  • September 6, 2017: Sahel rainfall response to a uniform oceanic warming
    Yi Ming (GFDL)
    Coupled climate models project future changes to rainfall in the African Sahel ranging from severe drying to severe wettening. Atmosphere-only models perturbed with uniform ocean surface warming span a similar range, motivating study of the simpler latter problem in order to constrain the more societally relevant former one. We analyze four comprehensive atmospheric models developed at the NOAA Geophysical Fluid Dynamics Laboratory, which respond to uniform ocean surface warming of 2 K with Sahel wet season rainfall changes ranging from -38 to +15%. A detailed MSE budget analysis reveals the relative importance of different processes in determining the response.

  • October 4, 2017: Moisture-convection feedbacks and a precipitation equation for the Madden-Julian Oscillation
    Angel Adames (GFDL)
    Column moisture and moist static energy (MSE) budgets have become common tools in the study of the processes responsible for the maintenance and evolution of the MJO. While many studies have shown that precipitation is spatially correlated with column moisture, these budgets do not directly describe the MJO-related precipitation anomalies. Other spatially varying fields may also play a role in determining the horizontal distribution of anomalous precipitation. In this study, an empirical precipitation anomaly field is derived that depends on three variables in addition to column moisture. These are the low-frequency distribution of precipitation, the low-frequency column saturation water vapor, and the sensitivity of precipitation to changes in column relative humidity. The addition of these fields improve upon moisture/MSE budgets by confining these anomalies to the climatologically rainy areas of the tropics, where MJO activity is strongest. The derived field adequately describes the MJO-related precipitation anomalies, comparing favorably with TRMM precipitation data.
