Abstract: An empirical relationship between climatological sea surface temperature (SST) and the maximum intensity of tropical cyclones in the North Atlantic basin is developed from a 31-year sample (1962?1992). This relationship ...

Abstract: The method of model fitting, or ?adjoint method,? is tested in a barotropic hurricane track forecast model. The model vorticity field at the beginning of an assimilation period is adjusted to minimize a cost function that ...

Abstract: This paper investigates the interactions between two developing cumulonimbus systems and the boundary layer (surface winds, pressure, divergence and temperature fields) on a case study day, 25 August 1975. These two systems ...

Abstract: The in-cloud structure of radar reflectivity and vertical velocity from Doppler radar measurements are described for two cumulonimbus systems that developed over the FACE-1975 surface mesonetwork area on a case study day, ...

Abstract: Mean track forecast errors over the 6-yr period 1983?88 are compared for four tropical cyclone-track forecast models in use at the National Hurricane Center (NHC). The model types represented are statistical, statistical ...

Abstract: A numerical method for analysing and forecasting a wide range of horizontal scales of motion is tested in a barotropic hurricane track forecast model. The numerical method uses cubic B-spline representations of variables ...

Abstract: he Dvorak technique is used operationally worldwide for tropical cyclone intensity analysis. This study tests Dvorak intensity change constraints, using a database of simultaneous aircraft and satellite fixes for tropical ...
