Potential Central America participation during NAME

to improve available daily precipitation data for near-realtime analysis in tiers 2, and 3.

to supplement radio-sonde observations to twice-daily

A proposal is to be submitted through CRRH to potential funding agencies (CRUSA,….)

Guatemala, Honduras, El Salvador, and Costa Rica have shown written interest to participate in NAME

4. Future work

Non-ENSO signals

Role of the warm pools in convective activity (Are changes in SST associated with changes in convective

activity and the MSD?)

Geographical extent of the MSD and its impacts on agriculture, hydropower generation, etc. (ENSO related?)

Importance of the Caribbean Low Level Easterly –Jet(CALLE-Jota) in the westward and northward transfer of properties (momentum and moisture, ...); interaction of jetwith easterly waves,…
