Title

APPLICATIONS OF THE INSTABILITY INDICES FOR DETECTION AND DYNAMIC ANALYSIS OF 25 APRIL 2010 THUNDERSTORM IN TABRIZ

Pages

  182-208

Abstract

 The probability distribution of THUNDERSTORM occurrence in TABRIZ indicates the irreversibility of their occurrence chiefly, in short time return periods and therefore, THUNDERSTORMs and their resulting secondary features is regarded to be a permanent hazard in TABRIZ. Different ATMOSPHERIC INSTABILITY INDICES are used for THUNDERSTORM evaluation. In this paper the Convective Available Potential Energy (CAPE), Convective Inhibition Energy (CIN), Showalter Index (SI), K Index (KI), Total Totals Index (TTI), Lifted Index (LI), Soaring Index (SI), Severe Weather Threat Indicator (SWEAT) and Perceptible water (PW) indices are used for evaluation of 25 April 2010 occurred THUNDERSTORMs in TABRIZ. The applications of instability indices demonstrated that all indexes confirm occurrence of sever atmospheric instabilities which are in THUNDERSTORM scale from severity point of view. The results of application of instability indexes showed that Showalter Index From amongst all indices is the best index in TABRIZ sample weather. Also, intensification and movement of atmospheric instability and vertical convection in three 650, 700 and 750 Hpa levels on May 5 prove that the occurrence of THUNDERSTORM, 18 mm rainfall and hail in these days cannot only cause instability in the local air Azerbaijan spring convection the instability and severe THUNDERSTORM occurrence of new air mantle and synoptic factors have been conducted.
