Effect of ENSO on Seasonal Temperature Over Tamil Nadu

M. Rajavel, M. Vengateswari, V. Geethalakshmi, K. Bhuvaneswari, V. Vakeswaran, R. Gowtham & S. Priyanka · International Journal of Environment and Climate Change · 2022

Increased concentration of greenhouse gases is expected to alter the radiative balance of atmosphere, causing increase in temperature and changes in precipitation patterns. Climate variability has been principal source of fluctuations in Indian food production. Even though there...

Deviation in Occurrence of Climatic Drought Over Western Zone of Tamil Nadu

M. Rajavel, C. Pradipa, K. Bhuvaneeshwari, V. Guhan, V. Vakeswaran, R. Gowtham & S. Prinyanka · International Journal of Environment and Climate Change · 2022

Drought is the major precipitation anomaly that has greater impact on water resource management, ground water table and agricultural production. The WASP index (Weighted Anomaly of Standardized Precipitation Index) was estimated for a period 1901-2019 (119 years) – four time scal...

Estimation of Meteorological Drought in Bhavanisagar Block using Weather Cock Software as a Tool

M. Rajavel, V. Guhan, V. Vakeswaran, K. Bhuvaneswari, R. Gowtham & S. Priyanka · International Journal of Environment and Climate Change · 2022

Drought happen aimlessly and there is no periodicity in its event and can't be anticipated ahead of time. In semiarid stations, the event of precipitation is occasional and is known something else for its changeability regarding reality. Meteorological drought is characterized as...

Estimation of Reference Evapotranspiration in Bhavanisagar Block of Tamil Nadu Using FAO ETo Calculator

M. Rajavel, V. Guhan, V. Vakeswaran, K. Bhuvaneswari, R. Gowtham & S. Priyanka · International Journal of Plant & Soil Science · 2022

The FAO Penman-Monteith equation is used by the ETo calculator software to calculate reference evapotranspiration – ETo from meteorological data. FAO chose this technique as the standard because it is physically based, roughly approximates grass ETo in the studied region, and exp...
