PM2.5 diminution and haze events over Delhi during the COVID-19 lockdown period: an interplay between the baseline pollution and meteorology.
Surendra Dhaka,Chetna,Vinay Kumar,V. Panwar,A. P. Dimri,Narendra Singh,Prabir K. Patra,Yutaka Matsumi,Masayuki Takigawa,Tomoki Nakayama,Kazuyo Yamaji,Mizuo Kajino,Prakhar Misra,Sachiko Hayashida +13 more
TL;DR: A highly complex interplay between the baseline pollution and meteorology leading to counter intuitive enhancements in pollution, besides an overall improvement in air quality during the COVID-19 lockdown in this part of the world is highlighted.
Journal ArticleDOI
Gravity wave generation in the lower stratosphere due to passage of the typhoon 9426 (Orchid) observed by the MU radar at Shigaraki (34.85°N, 136.10°E)
Surendra Dhaka,Surendra Dhaka,Masaaki Takahashi,Yoshiaki Shibagaki,Manabu D. Yamanaka,Shoichiro Fukao +5 more
TL;DR: In this article, the intensity of gravity wave activity in the lower stratosphere during the typhoon 9426 was investigated in the MU radar site, and the vertical wavelength of these waves was examined from 2.5 km to 4.0 km.
Journal ArticleDOI
Observable signatures of a convectively generated wave field over the tropics using Indian MST radar at Gadanki (13.5°N, 79.2°E)
Surendra Dhaka,Surendra Dhaka,R. K. Choudhary,S. Malik,Yoshiaki Shibagaki,Manabu D. Yamanaka,Shoichiro Fukao +6 more
TL;DR: In this article, an experiment was conducted in the month of June 2000 to study the atmospheric dynamical behavior in the troposphere and lower stratosphere in the presence of a cloudy and moist background environment due to the onset of the summer monsoon over Indian peninsula.
Journal ArticleDOI
Boundary layer evolution over the central Himalayas from radio wind profilerand model simulations
Narendra Singh,Raman Solanki,Raman Solanki,Narendra Ojha,Ruud H. H. Janssen,Andrea Pozzer,Surendra Dhaka +6 more
TL;DR: In this article, the authors investigate the time evolution of the Local Boundary Layer (LBL) for the first time over a mountain ridge at Nainital (79.5°E, 29.4°N, 1958 m)a.s.l.
Journal ArticleDOI
Indian MST radar observations of gravity wave activities associated with tropical convection
TL;DR: In this article, MST radar observations at Gadanki (13.5° N, 79.2° E ) of high frequency (few tens of minutes) gravity waves generated most likely by convection are presented.
