The long-term variations in foF2 at Hobart (52.88°S, 147.32°E), Canberra (35.28°S, 149.13° E) and Christchurch (43.53°S, 172.64°E) stations, located in the mid-latitude zone in the Southern Hemisphere were analyzed using 1947–2006 years of the data. The saturation, solar and geomagnetic activity and seasonal effects were removed mainly by using 12-...
Article
The sea surface temperature (SST) and upper-ocean heat content (OHC) have been explored along the track of two tropical cyclones (TCs): TC Pam (2015) and TC Winston (2016). These TCs severely affected the islands of Vanuatu and Fiji, in the South Pacific region (8°–30°S, 140°E−170°W). The SST decreased by as much as 5.4°C along the tracks of the TC...

The observations of vertical total electron content (VTEC) and L1 and L2 band ionospheric scintillations at an equatorial station, Tarawa (Geomag. Coordinates, 2.68ºS, 114.26° W), Kiribati, under a complex severe space weather event of 4–9 September 2017, are presented. The VTEC increased significantly by 1.03 and 1.31 TEC units under M5.5 flare at...

... Climate change also plays a significant role in determining the quality of groundwater in PICs. The sea level rise, frequency and severity of tropical cyclone occurrence, amount of rainfall and net recharge patterns, atmospheric heat, carbon dioxide (CO 2 ) emissions and Tsunami can be linked with climate change in PICs (Sharan and Kumar, 2021;. All these environmental issues can be inked with the SWI in PICs. ...
