Prediction of summer monsoon rainfall over India and its homogeneous regions

Abstract: ABSTRACT:The coherent regions for various fields such as sea level pressure, temperature, geopotential height and zonal wind anomalies at the surface, 850, 500 and 200 hPa levels in pre-monsoon months (January through May) and seasons (winter, spring) have been identified by applying the shared nearest neighbour algorithm. The fields over the corresponding cluster regions could be possible predictors for Indian summer monsoon rainfall as well as the rainfall over various homogeneous regions of India. The time … Show more

“…The geo-potential height of north-western and central Russia above the Indian subcontinent and the region of Artic Ocean above the longitudinal stretch of Russia are ascertained as the predictors of north-west India. The same region of Artic Ocean over Russia was also identified by Kakade and Kulkarni (2016) for influencing north-west Indian monsoon. A combination of the regions of the North Pacific Ocean and South Atlantic Ocean is also evaluated as an important monsoon predictor.…”

“…Regional prediction of the Indian subcontinent has also been attempted with the application of canonical correlation analysis (Sinha et al 2013). Recently, Indian Institute of Tropical Meteorology, Pune has performed the aggregate Indian monsoon prediction along with the prediction of its regional sub-divisions using shared nearest neighbour clustering approach (Kakade and Kulkarni 2016). Their method has engrossed the non-linear connections between seasonal monsoon and cluster parameters along with the linear relations, and has provided promising prediction accuracies.…”

“…This algorithm identifies the clusters of different shapes, sizes and densities. Kakade and Kulkarni (2016) described the SNN algorithm to obtain cluster regions of various meteorological fields. In this paper, an attempt has been made to identify the regions of India depending upon monsoon rainfall over sub-divisions of India.…”

“…Thus evolution of AO pattern, in contrasting phases of ESI-tendency, is exactly opposite. The relationship between predictor and ISMR drastically changes with the phase of ESI-tendency [31]. So here we have considered association of CTSs with ISMR during opposite phases of ESItendency.…”
