Detailed Analysis of A Tropical Cyclone Simulated with a 13-Layer Model
نویسنده
چکیده
A numerical experiment for the study of the development and the structure of tropical cyclones is performed with a 13-layer model. The total amount of latent heat released in a vertical column of air is specified by the horizontal mass convergence in the friction layer, as proposed by Ooyama (1964) . The vertical distribution of released latent heat is assumed to be proportional to the temperature difference between cumulus clouds and large scale field (Yamasaki, 1968b). For simplicity, the equivalent potential temperature of cumulus clouds is kept constant with time and space. The numerical experiment shows that the present tropical cyclone model is capable of describing many features observed in actual tropical cyclones, if initial conditions (especially the initial static stability) and various physical parameters are chosen appropriately. The structure and the developmental process of the simulated tropical cyclone are discussed in detail.

Tropical cyclone Haiyan (TCH) that formed over the West Pacific Ocean during 3-11 November 2013 has been investigated using three datasets produced by Japan Meteorology Agency, ECMWF and NCEP. Strength of TCH has been studied using two synoptic parameters of 10-m wind velocity and mean sea level pressure (MSLP). Following, three dynamic parameters including vertical wind shear (VWSH) vector, he...

Understanding the processes that contribute to tropical cyclone (TC) formation, intensity and structure changes is essential for improving the predictability of TCs. Previous studies have focused mostly on the lowto mid-level processes leading to TC formation and rapid intensity and structure changes. The influence of upper-level atmospheric processes, especially the evolution of the outflow la...
متن کاملSensitivity of Tropical Cyclone Intensity to Ventilation in an Axisymmetric Model
The sensitivity of tropical cyclone intensity to ventilation of cooler, drier air into the inner core is examined using an axisymmetric tropical cyclone model with parameterized ventilation. Sufficiently strong ventilation induces cooling of the upper-level warm core, a shift in the secondary circulation radially outward, and a decrease in the simulated intensity. Increasing the strength of the...

[1] Using the AIRS retrieved temperature and humidity profiles, the Saharan Air Layer (SAL) influence on the formation of Hurricane Isabel (2003) is simulated numerically with the MM5 model. The warmth and dryness of the SAL (the thermodynamic effect) is assimilated by use of the nudging technique, which enables the model thermodynamic state to be relaxed to the profiles of the AIRS retrieved d...
