Tidal wind oscillations in the tropical lower atmosphere as observed by Indian MST Radar
Diurnal tidal components in horizontal winds measured by MST radar in the troposphere and lower stratosphere over a tropical station Gadanki (13.5 N, 79.2 E) are presented for the autumn equinox, winter, vernal equinox and summer seasons. For this purpose radar data obtained over many diurnal cycles from September 1995 to August 1996 are used. The results obtained show that although the seasona...
متن کاملA study of tropical tropopause using MST radar
Using the MST radar data of vertical wind, the characteristics of the tropical tropopause, following four different definitions, depending on 1) temperature lapse rate, 2) cold point, 3) convective outflow and 4) potential temperature lapse rate minimum, are studied. From the vertical wind data of the radar, the altitude profiles of temperature and horizontal divergence are derived, from which ...
متن کاملOptimum Tilt Angles in Two Dimensional Phased Array Radar Systems
In phased array antennas, the number of radiator rows is one of the important factors to minimizing both cost and weight. Therefore, the antenna tilt angles having relation with the element spacing are among the important design parameters. In this paper, the optimum tilt angles for several types of dipole planar arrays are investigated theoretically. To obtain optimum tilt angles, the directiv...
متن کاملEstimation of temperature and humidity from MST radar observations
Retrieval of vertical profiles of temperature and humidity parameters using a VHF radar is described in this paper. For this, Indian MST radar located at Gadanki (13.5◦ N, 79.2◦ E) has been operated in a special mode. First, vertical velocities are collected continuously using the radar and are subjected to Fast Fourier Transform (FFT) analysis to obtain Brunt-Väisälä oscillations. From the mea...
متن کاملTropical Cyclone Wind Estimation Using Synthetic Aperture Radar
We have investigated various SAR images of tropical cyclones, which were acquired by the SAR aboard the satellites ENVISAT and RADARSAT-1 at different polarizations and incidence angles, using a similar approach as suggested by Horstmann et al., 2005 [1]. The resulting SAR-retrieved wind fields are compared to results of high-resolution numerical models as well as in situ measurements collected...
