In the context of climate change, extreme precipitation in semi-arid region happens frequently. How well models simulate remains unclear. Based on a WRF v4.3 simulation rainstorm event that occurred Qingyang, China 21 July 2019, applying Kain–Fritsch (KF), Grell–Devenyi (GD) and Bullock–Wang (BW) schemes, impacts different cumulus parameterizations simulations were analyzed, possible causes bia...

BSERVATIONS on X-irradiation induced X-Y nondisjunction and exchange in spermatocytes of Drosophila have been made by STRANGIO (1961, 1962) and by ZIMMERING and Wu ( 1963,1964), both using the doubly marked Y chromosome, BS Y y+ (BROSSEAU, NICOLETTI, GRELL, and LINDSLEY 1961), and by SAVHAGEN (1961) who employed the singly marked Y chromosome, y+ Y (= scs. Y of MULLER 1948). The criterion for n...

HE detection, by agar gel electrophoresis, of as many as ten alcohol dehydrogenase isozymes in Drosophila melanogaster (URSPRUNG and LEONE 1965) presents a problem in the interpretation of genetic and epigenetic control of synthesis and function of multiple forms of enzymes. The observation that the three slowest cathodalIy migrating isozymes show a more intensive formazan staining when primary...

Severe local storms, including tornadoes, damaging hail and wind gusts, frequently occur over the eastern and northeastern states of India during the pre-monsoon season (March-May). Forecasting thunderstorms is one of the most difficult tasks in weather prediction, due to their rather small spatial and temporal extension and the inherent non-linearity of their dynamics and physics. In this pape...

This study investigates the sensitivity of simulated tropical cyclones (TC) affecting Philippines to convective parameterization schemes (CPS) in Regional Climate Model Version 4 (RegCM4). Five ERA-Interim driven RegCM4 simulations at 25-km horizontal resolution were conducted utilizing CPS Grell with Arakawa–Schubert closure (GR), Emanuel (EM), Kain–Fritsch (KF), Tiedtke (TE), and a combined s...

This study simulates an unusual extreme rainfall event that occurred in Salvador city, Bahia, Brazil, on December 9, 2017, which was named subtropical storm Guará and had precipitation of approximately 24 mm within less than 1 h. Numerical simulations were conducted using the Weather Research Forecasting (WRF) model over three domains with horizontal resolutions 3, km. Different combinations se...
