      Dear Dr Rodrigues,
      I am glad to know that you found my blog useful. But let me clarify a few things:
      I am Dr Ranjan Kelkar, a retired scientist, living in Pune. I am not a Hindu but very much a Christian.
      It was my father, Ratnakar Hari Kelkar, who made his own translation of the Marathi New Testament from the original Greek. I have only made it available online at https://marathibible.wordpress.com
      Very recently, I have published my own book in Marathi entitled “Khristi Dharmachi Olakh”, an introduction to Christianity from an Indian perspective. It is available on Amazon.
      With my regards,
      Ranjan Kelkar

    Respected Sir,
    I am Divya Prakash, Research Scholar at Centre of Excellence in Climatology, Birla Institute of Technology, Mesra. Sir, I would be grateful to know the method for calculating the normal rainfall. This question came in my mind because I noticed that in case of East Rajasthan, the normal rainfall during Monsoon 2009 was 623.6 mm while actual rainfall was 430.1 mm with deficient of 31% (http://www.imd.gov.in/section/hydro/dynamic/rfmaps/seasonal/mon2009.jpg). But in case of 2010, the normal rainfall of East Rajasthan increases to 630.3 mm (http://www.imd.gov.in/section/hydro/dynamic/rfmaps/seasonal/mon2010.jpg). When rainfall was excess during Monsoon 2010 after that the normal rainfall for Monsoon 2011 decreased to 615.8 mm. During 2009 the rainfall was deficit then I am not understanding why the normal rainfall increased in 2010.

      Dear Divya Prakash,
      I think you are referring to the rainfall reports that are generated operationally and put on the web site. These normals and actuals are area-weighted. So they may differ from year to year depending upon the configuration of stations in particular years. The main purpose of these operational reports is to bring out the departures from normal. If you are more interested in the normals themselves, please see this link http://www.imd.gov.in/section/nhac/dynamic/advertisement_district_rf_series.pdf

      Jan 11, 2013 @ 10:00:54

      Dear Shiar,
      Ladakh is an area of low rainfall and, therefore, flash floods caused by intense rain are rare events. In fact, the August 2010 flash floods came as a surprise to many. Because there have hardly been any past (documented) events of this nature, it is very difficult to generalise the causes in terms of amount or intensity of rain, as you wish to do.
      Flash floods do occur more frequently in Himachal and Uttarakhand, usually due to cloudburst. I suggest that you get in touch with research institutions in these states and draw parallels from their studies. If you go to Google Scholar you may find relevant research papers. You may also like to refer to the work done by ICIMOD in Nepal.
      Predicting rare events is always tough. More so in the case of cloudburst over Ladakh, which may not happen hopefully for many more years!

    I am Abira Dutta Roy, a research scholar from Jawaharlal Nehru University, New Delhi.I am working on a hydrological model called SWAT. In the model with the help of climatic parameters such as maximum minimum temperature, rainfall, relative humidity, solar radiation and wind speed together with land use, soil, ground water data I can simulate runoff. The model runs on daily time step. I wanted to compute normal daily temperature, normal daily wind speed, daily normal rainfall etc. and look into how with normal weather conditions and changing land use land cover conditions the runoff changes.calculating daily normal temperature , solar radiation, wind speed etc was not a problem as they are simple averages. I am facing problem in computing daily normal precipitation.
    If I compute a simple average, everyday is experiencing a certain amount of rainfall, which is not the case in reality. To capture the real situation i thought of estimating the probability of occurrence of rainfall in a particular day . But that too i dont feel is the right way of calculating it.

    Sir i have emailed you too all the details . Please help me find a solution to this. i will be grateful

      Dear Abira,
      First of all, you should discuss such problems with your guide and I hope you have one. If you don’t have a guide you will be in serious trouble. These days it is easy for anyone to download any model and to run it anywhere without understanding it. This is just “garbage in garbage out”.
      Secondly, SWAT is basically a hydrological model that predicts runoff in a watershed or river basin, given the weather parameters. You have not told me on which region you are working so I have no idea of the likely precipitation.
      Then, you seem to be using the model in the sense opposite to its purpose. You are trying to estimate precipitation from the runoff, if I understand you properly. Further, you are trying to get annual normals from a model that has a 24-hour time step. How is that possible?
      Since you are working in JNU and apparently you are not getting much guidance there, I suggest that you read papers about the applications of SWAT, its limitations and potential use, and some case studies for India. Maybe you have to visit a library for that purpose. Google search is not the solution for every problem.
      If you continue to work in the way you are doing now, I am afraid you will get absurd results.
      Best wishes,
      R R Kelkar

      Dear Rishabh,

      First of all let me congratulate you, your fellow students and your teacher for designing an excellent web site on the rain and monsoon of India. It has excellent content but what really impressed me was its professional look. I have written a post about your web site in this blog.

      Keep it up!

      Best wishes,

    Dear Sir,
    I have interacted with you earlier regarding the latest updated version of Indian Climatological tables book. As per your advice i have contacted the Mausam Bhawan(Library section) and they say that the latest copy available with them is of data from 1951-1980, the same copy is available in our library too and also i was apprised of a new book being published with data of weather from 1961-1990. Sir, your previous blog suggested an updated version of weather data available upto the year 2000.Sir, Kindly let me know if any such hard copy exists as the latest data would help us a lot in our projects.

      Dear Mr Bhargava Ram,

      If you click on the link http://www.imd.gov.in/doc/climateimp.pdf you will be able to see a pdf file of “Monthly mean maximum & minimum temperature and total rainfall based upon 1901-2000” for 122 stations in India.
      If you want month by month (not mean) data you can click on http://www.imd.gov.in/section/nhac/mean/110_new.htm.
      You can then take prints yourself.

      Will that be helpful to you?

      Regards,

      Kelkar

    Respected Sir ,

    I am proud to be student of teacher like you who despite having achieved that not many can , helps people through blogs .

    In one of the latest update in your blog , you have mention the image of meteorologist in the common public. But I think we are not doing enough to improve that . Latest example of cyclone Phyan . Do you think the track prediction was upto the mark . Did not we did abysmally bad ? I will be happy to see your comment on it .

    Thank you

      It was nice to hear from you. Hope you are doing well. What you say is very pertinent, but as a rule I do not get involved in operational matters which are IMD’s responsibility and best left to them.

    Dear Dr. Kelkar,
    I am a practicing architect from Pune for past 15 years. Currently I am perusing my masters degree in Environmental Architecture. As a part of the study for this course, I was browsing through various pages related to climate. I also had particular requirement of climatic data of Shreevardhan in Konkan where i am proposing a project as a part of the course study. While surfing on the net, i came across your blog. I was amazed to see your enthusiasm in starting the blog and also to see the replies sent by you to various queries with great patience!

      Dear Rakesh,

      I have visited your site off and on. It is nice, but you take a lot of information from other sites and you do not always give due acknowledgement. If you want to develop an online weather community, you should not copy everything into your site, but describe what information other sites have and provide links to them.

      Good luck

    I really enjoyed browsing through your pages. Your blog is such a treasure trove of information on Indian meteorology. I would appreciate if you can devote some time and energy on meteorological education and training in India, and find a way to inspire bright young students to pursue careers in meteorology, both in operations and research.

    I am happy to know that you are planning to write a book on climate change with focus on India. Please do not hesitate to contact me if you need any help in your efforts.

    All the best,

      Dear Dr Rupa Kumar,

      How nice of you to write your words of appreciation about me and my blog. It is indeed a popular blog and in the last two years there have been over 37,000 hits.

      Two of my books on Satellite Meteorology and Monsoon Prediction have been selling well and that has encouraged me to take up writing this book on climate change. My idea is to present a balanced view of climate change and not a one-sided scary scenario as is often done. I have your paper on the PRECIS simulation but if you have any updates I would be happy to have them.

      I used to teach at the University of Pune until Dec 2008 when I retired after crossing 65 years.

      Regards and best wishes,

    Dear Dr Kelkar,

    I am writing an anthropology paper about how geography influences culture, in this case, the culture of the people of the Deccan Plateau in India. I am focusing on the use of solar power. I saw a figure (and lost the specific URL) on the internet saying that they have a high percentage of sunny days enabling them to benefit from solar sources. I can’t locate this information on percentage of sunshine per year, can you help me? I could benefit from this information in a smaller area, I could limit it to a city i.e. Bangalore.

    Sincerely,

    Dear Sir,
    I have been visiting your blog regularly and would like to thank you for all the enlightening postings.

    I am a film student/film maker from Satyajit Ray Film and Television Institute, kolkata. In few weeks from now, I will be shooting my thesis film. The film is driven by the protagonist’s passion for rain … and her accidental meeting with a woman farmer who helps widen her world view.

    For the film, I need weather satellite maps/ weather maps which indicate dense cloud over kerala to indicate the onset of monsoon. It means that I need archival material/ images of 25th May onwards. Where can I find them? Any suggestions?(www.weather.nic.does not have a archive).

    Does IMD give archival materials/images to be used only for academic purpose?

    I am very eager to send a copy of the film when I finish it. It has a song being written and composed on Rain!

    Thanking you

    With regards

    Dea rrkelkar sir
    The write up is beautiful never knew that Simla office existed in Pune. Pray accept my congratulations on the article. However you did mention that Kennedy house is no longer there. I beg to differ . I did my schooling and college education from Simla before completing engg from IIT Madras in 67. In our time while going to school ( Har Court Butler ) we had to pass the Kennedy House building which housed the labour commission branch . Next to this building Kennedy cottage was built during the war to house Insurance Dept Minsitry of Finance . My father retired from that office in 1975 as Deputy Controller of Insurance. The Kennedy House was located on the Mall road near to the main road to Ananadale groaund down below – a motorable road that could take in Army 3 tonner trucks.
    I still distinctly remember the building . I hope you were referring to the same building.
