IMD brings out publications on varied meteorological topics. Some of the latest publications are as follows which are also available free online on our departmental website.
The Climatological Tables give normal values for 0830 hours IST and 1730 hours IST for various meteorological parameters viz. Humidity, wind, cloud, visibility, etc. It also gives a comprehensive account of the climate of a place month wise with extremes in the temperatures and rainfall and annual averages. The present publication is based on data of the 416 stations from all over India for the period 1981-2010. Previous editions of this book i. e. (1931 - 1960), (1951- 1980), (1961 - 1990), (1971 - 2000) are also available

Wind Rose is a method of graphically, representing the occurrence of winds at a location, showing their strength, direction and frequency. This publication providing wind roses of surface winds measured at 0300 UTC and 1200 UTC during 1971-2000 at surface met. Observatories under IMD Network. It contains monthly and annual wind roses for 180 stations. Atlas of wind Roses: (1971-2000) Vol I Part A 0300 UTC, Atlas of wind Roses: (1971-2000) Vol I Part B 0300 UTC, Atlas of wind Roses: (1971-2000) Vol II Part A 1200 UTC, Atlas of wind Roses: (1971-2000) Vol II Part B 1200 UTC,
This publication gives at a glance information of spatial distribution of weather parameters (Height/pressure , temperature and upper winds etc.) over India. It has been updated utilizing upper Air data for the period 1971-2000 and contains analysed charts (0000 UTC & 1200 UTC) on height (gpm), temperature (C) and upper winds for six standard pressure levels 850,700, 500, 300 ,200& 100 hpa for four representative months of the seasons. Besides it contains height pressure of freezing Level. The upper wind pressure charts exhibit streamlines cyclonic and anticyclonic circulation, isotachs and jet streams circulation. Also other publications are also available related to this subject viz; Monthly Normals of RAWIN Winds based on morning and evening data (1971-2000)(0530IST), Monthly Normals of Radiosonde and Radiowind for Indian Stations (1730IST), (0530IST), Monthly Normals of Radiosonde and Radiowind for Indian Stations (1971-2000)(1730IST), (1971-2000)(0530IST)etc.
The present publication is based on the Rainfall Normals for the period 1951-2000 of 2399 well distributed rainguage stations in India. The present atlas contains 95 rainfall maps.
The publication gives summary of natural hazards viz; Floods and Heavy Rains, Snowfall, Cold and Heat wave, Dust storm, Thunderstorm, Cyclonic Storm Drought etc. is based on various reports of the IMD and press information.

This book meets a long felt requirement of solar energy users in India. The data pertaining to solar radiant energy available in this book, it helps to the designers of solar energy power systems. In this book the data period covered is from 1986 to 2000
The data used to prepare the summary charts were obtained from two sources (i)
Weather observations recorded by Indian VOF & (ii) Weather observations recorded by other shops while in the Indian
area of responsibility but passed on the other member countries of MCSS. The charts are prepared using Genetic Mapping
Tools. For the presentation of climatological data , a chart with spatial domain bounded between 15S-40N and 20E- 100E
has been used. Following previous editions of this book are also available ;
• Marine Climatological Summary Charts (1991-2000), (1971 –1980)
• Marine Climatological Atlas (1961-1990)
• Marine Climatological Summary 1961 to 1970 (annual)
This publication published in 1981. It contains all titles issued from 1875-1993 of IMD. The Catalogue gives the information of Memoirs of IMD, Atlases and charts, Cyclone Memoirs, Met Monographs, Scientific and technical Notes, etc.
