Real-time nowcast of a cloudburst and a thunderstorm event with assimilation of Doppler weather radar data

Srivastava, Kuldeep; Bhardwaj, Rashmi - In: Natural Hazards 70 (2014) 2, pp. 1357-1383

Extreme weather events such as cloudburst and thunderstorms are great threat to life and property. It is a great challenge for the forecasters to nowcast such hazardous extreme weather events. Mesoscale model (ARPS) with real-time assimilation of DWR data has been operationally implemented in...

MODULATIONS IN LOW-TEMPERATURE TRANSIENT REFLECTIVITY MEASUREMENTS

KHAN, SALAHUDDIN; CHARI, RAMA; JAYABALAN, J.; PAL, SUPARNA - In: Surface Review and Letters (SRL) 21 (2014) 01, pp. 1450005-1

Periodic modulations that appear in the low-temperature transient reflectivity signal of a GaAsP/AlGaAs single quantum …. Jpn. 76 (2007) 123702(1–3).] We show that such periodic modulations are caused by changes in the linear reflectivity of … the sample during transient reflectivity measurements. Studies carried out on reflectivity of different materials under …
