Understanding Year Wise Deviation and Trend of Monthly Value of Meteorological Parameters for Some Cities in India for the Month of April in Comparison with Normal by AIML

Sumana Chatterjee

This paper is based on research study with meteorological parameters related with monthly day summary data from historical years since 1969 till 2026. The month of study was the month April. The data collection platform was ‘Data supply platform IMD Pune’. The stations under study were some important cities in India. The historical meteorological day summary monthly data for some important meteorological parameters for each city were collected similarly since 1969 till 2026 along with corresponding historical record of monthly normal values for those meteorological parameters for those cities for analysis. The study was to understand the deviation of monthly value of these parameters from the monthly normal value of the same parameters since 1969 till 2026 and also to understand the predicted trend of the deviation of the same parameters for recent future years. For better understanding of the pattern change or deviation from past as well as understanding of future trend of the deviation of those meteorological parameters through all over India, data for cities from all parts of India  among which Srinagar and Shimla from north, Jaipur and Mumbai from west, Bhubaneswar and Kolkata (Alipore) from East , Chennai and Bengaluru from south and Delhi as city from central part of India were chosen whose historical monthly data were collected for the analysis with python programming language on google collaborator platform. The meteorological day summary data, for these cities and monthly deviation from normal for the parameters MMAX, mean maximum  temperature in 0c, HMAX, highest maximum temperature in 0c, MMIN, mean minimum temperature in 0c, LMIN, lowest minimum temperature in 0c, TMRF, total rainfall in the month in mm, RD, number of rainy days in the month having rainfall more than 2.4 mm ,MWS, mean wind speed in kmph,P2, number of days with precipitation 0.3 mm or more and also for HA,TH,FG,DS,SQ, respectively number of days with hail, thunder, fog, dust storm data in month ,were collected for those cities for this analysis with concerned month APRIL under study.
