National Meteorological Center, 20233, Washington, D.C., USA aut Tropical storm motion and structure in a fine mesh primitive equation model [Elektronische Daten] [M. Mathur] Summary: Convective to planetary scale processes govern the motion and structure of tropical storms. A model with a high resolution and a large domain is required for accurate prediction of a storm's track and intensity. A series of integrations are performed using a primitive equation model and an initial state that defines a tropical storm that later developed into a hurricane in the real atmosphere. Increasing the horizontal resolution or domain of the model improves the forecast track. However only the increase in the horizontal resolution produces a better hurricane structure. Banded structure in the vertical motion field, asymmetries in the low tropospheric winds similar to those observed and upper tropospheric cyclonic outflow develop in high horizontal resolution experiments. It is shown that horizontal advection and pressure gradient terms produce wind tendencies in the low troposphere that displace the vortex in the observed direction. A high pressure area surrounding the central low pressure area appears in the upper troposphere. Around this high pressure area large pressure gradients develop that induce outflow winds in the distal storm area.
