NAMMA - NASA African Monsoon Multidisciplinary Analyses

The NASA African Monsoon Multidisciplinary Analyses (NAMMA) campaign was conducted primarily to explore the relationship between African Easterly Waves (AEWs) and tropical cyclogenesis in the Atlantic basin, as well as the role of the Saharan Air Layer (SAL) in modulating the intensity of the waves and tropical cyclone growth.

The CSU Radar Meteorology Group, in cooperation with NASA Wallops Flight Facility, was responsible for the deployment of the TOGA radar during NAMMA. The TOGA radar was located near Praia, Sao Taigo in the Republic of Cape Verde. The radar collected data nearly continuously from 15 August - 16 September 2006.

TOGA was deployed primarily to:

• Assist in the guidance of the NASA DC-8;
• Analyze precipitation and circulation structures within maritime mesoscale convective systems (MCSs) in the vicinity of the Cape Verde islands and describe the progression of their structure and behavior as they transition from the African continent to a more maritime environment; and
• Document kinematic, microphysical, and precipitation features, internal to these MCSs, that are relevant to tropical cyclogenesis.
