LAGRANGIAN DYNAMICS AND LOW LATITUDE WEATHER,
Abstract
The differential equations of horizontal motion of the atmosphere with variable Coriolis parameter have been integrated numerically for both frictionless flow and flow which incorporates a coefficient of surface frictional resistance, to obtain trajectories of air parcels which move through observed meridional pressure gradient profiles within the tropics. Convergence patterns have been computed from the trajectories of adjacent air parcels which are initially at a fixed distance apart. Good agreement has been obtained between the convergence computed by following the flow and the rainfall and cloudiness observed by satellites and surface weather observations for case examples on both synoptic and climatological time scales in the South Central Pacific and the Indian Ocean.
