Observations of Coastally Transitioning West African Mesoscale Convective Systems during NAMMA

Table 1

Events selected for analysis are presented, and the parameters listed include the system type (TCP or NTCP), the date of NPOL observation, the time span in universal time, and the radiosondes that were launched during each of the cases. TCP (NTCP) refers to systems that produced (did not produce) tropical cyclones. The emboldened cases represent the most representative events for each case type.
