Abstract

Extreme events, while rare, are important because of their catastrophic impacts, which affect livelihood and soci-economic conditions. In order to identify anthropogenic impacts on the climatic variables, it is necessary to separate them from natural variability, which manifests as multi-decadal oscillations. This study examines multi-decadal oscillations by using Quantile perturbation Method (QPM) in temperature and precipitation time series to identify temporal trends and the anomalies that may be attributed to human impacts. Assessment of temperature and precipitation trends of major Tier I (Ahmedabad, Bengaluru, Chennai, Hyderabad, Kolkata, Mumbai, Lucknow, Ranchi, Srinagar, Tiruchirappalli, Thiruvananthapuram, and Visakhapatnam) Cities of the country sprawled across the geographical boundaries of peninsular India (North, East, West , and South) have been carried out. The long-term trend study has been performed by using Quantile Perturbation Method (QPM) and Mann-Kendall trend test. The precipitation and temperature data are extracted from the University of East Anglia Climate Research Unit’s (UEA-CRU) archive at Centre for Environmental Data Analysis. The assessment reveals significant anomalies in both the temperature and precipitation variables across the cities studied.
