aircraft reconnaissance of winter coastal cyclones in the northeastern United States1

During the 1966–67 and 1967–68 winter seasons, the ESSA Research Flight Facility carried out several weather reconnaissance missions in east coastal cyclones as part of a project on snow prediction in the northeastern United States. The operation of the aircraft program and the meteorological observations of primary interest are described. The aircraft reconnaissance system is found to be of significant potential value to east coast weather forecasters.
