1 Simulating an MJO Event using COAWST: CYGNSS Satellite Mission Support Xiaowen Li 1,2 Taka Iguchi 3,2 Stephen Nicolls 2 1 Morgan State University 2 NASA Goddard Space Flight Center 3 University of Maryland, College Park

2 Cyclone Global Navigation Satellite System Use delayed Doppler mapping instrument to measure sea surface roughness and retrieve sea surface wind

3 Madden-Julian Oscillation

4 Project Objectives: 1.To use DYNAMO field campaign as a pre-launch case study for CYGNSS mission, with the emphasis on the surface wind perturbations associated with organized convective systems. 1.To use the COAWST model output to derive synthetic CYGNSS data for the purpose of facilitating pre-launch researches and algorithm testing/development.

5 COAWST model simulation of DYNAMO October MJO event

6 COAWST model simulated DYNAMO October MJO event WRF WRF+ROMS Surface Rainfall Hovmoller Diagram, 30km resolution

7 COAWST model simulated DYNAMO October MJO event WRF WRF+ROMS SST Hovmoller Diagram, 30km resolution

8 COAWST model simulated DYNAMO October MJO event WRF WRF+ROMS Surface Rainfall Hovmoller Diagram, 4km resolution

9 COAWST model simulated DYNAMO October MJO event WRF WRF+ROMS SST Hovmoller Diagram, 4km resolution

10 COAWST model simulated DYNAMO October MJO event Surface Rainfall Hovmoller Diagram, 4km resolution WRF WRF+ROM

11 COAWST model simulated DYNAMO October MJO event WRF WRF+ROMS SST Hovmoller Diagram, 4km resolution

12 Future Plans Repeat the current case study using the latest COAWST release; Next step is to add SWAN model to the coupled COAWST simulations, and to compared model simulations with DYNAMO observations.
