The present study investigates the impact of northern mid-winter major stratospheric warming on tropical convection over Indian region by examining five Mid-winter Major Stratospheric Warming (MSW) events 2003/04, 2005/06, 2008/09, 2012/13, and 2018/19. dynamical variables like temperature, wind components, Outgoing Longwave Radiation are utilized from ECMWF ERA-Interim Reanalysis NOAA site. El...

With the assumption of radial motion and uniform longitudinal distribution of coronal mass ejections (CMEs), we propose a method to eliminate projection effects from the apparent observed CME latitude distribution. This method has been applied to SOHO LASCO data from 1996 January to 2006 December. As a result, we find that the real CME latitude distribution had the following characteristics: (1...

Using the University Navstar Consortium (UNAVCO) Global Positioning System (GPS) receiver network in North America, we present 2-D distributions of GPS radio signal scintillation mid-latitude ionosphere during 7–8 September 2017 storm. The showed a variety density structures such as storm enhanced (SED) base and plume, main trough, secondary trough early recovery phases. Enhanced phase amplitud...

We use data from the VIMS instrument on board the Cassini spacecraft to construct high sensitivity and high spatial-resolution maps of the locations of tropospheric clouds on Titan in the late northern winter season during which the Cassini prime mission took place. These observations show that, in this season, clouds on Titan are strongly hemispherically asymmetric. Mid-latitude clouds, in par...

Range shifts have been documented in many organisms, and climate change has been implicated as a contributing driver of latitudinal and altitudinal range modifications. However, little is known about what species trait(s) allow for faster environmental tracking and improved capacity for distribution expansions. We used data for 416 species of moths, and show that range limits in Sweden have shi...

in this study, the daily total ozone column (toc) measured by the instruments of toms (2001) and omi (2005-2011) satellites and brewer ground station (2002-2004) is used to investigate the extreme ozone mini-holes over esfahan. based on previous reports on validation of the toc data products, it is found that there is no problem with homogenization of data records, which was provided by the abo...
