Questions related to Tropical Meteorology
How can download the precipitation data from INDIAN METEOROLOGICAL DEPARTMENT(IMD) or Centre for Climate Change Research (CCCR) of Indian Institute of Tropical Meteorology
Could you refer to any other web sites?
The Madden-Julian Oscillation (MJO) event occurring earlier this year (2015) was said to be the strongest ever, based on its RMM index. I wonder if there is anyone ranking all the MJO events based on whatever criteria (e.g. RMM index, precipitation).
For predicting the future temperature in the Indian Himalayan Region, using IITM Cordex data or Worldclim (~1km Res) will be appropriate ?

Hi, is there any published paper that mentioned westerlies (pressure belt between 30 to 60 degree North latitude) shift south during the colder period and shift north during warmer (summer period).
One more paper that shows the Intertropical Convergence zone (ITCZ) during summer and winter in the Indian subcontinent.
Generally we know the precipitation increases as altitude increases and along the orography of the mountains also. How do you calculate this gradient in precipitation?
I am looking for the accurate location changes of ITCZ during the last 30 or 50 years. Have anyone done this work? Can you give some references?
We are performing nested runs with the WRF model to simulate weather over the equatorial Andes in South America. We are comparing model results against surface observations and sounding data. Since the WRF model works well for mid-latitude dynamics with the default options, I was wondering if it actually applies the right dynamics for equatorial regions. I am not sure if we are getting the right answers for the wrong reasons when we get good comparisons between the model and the observations.
To group literature data into semi-humid and humid tropical, I want to use the Coefficient of Variation for monthly precipitation (data source: worldclim). From which CV on, sites can be seen as semi-humid / humid?
I've got some wind speed measurements and I would like to find out which test is the most reasonable one to clarify if the data is stationary or not. Your help is highly appreciated.
The Safir-Simpson hurricane scale is a classification method to identify the intensity of a tropical cyclone by civil engineer Herbert Saffir and meteorologist Bob (Robert) Simpson, but this method proved to be useless due to its failures to identify the two thirds of the top 156 deadliest hurricanes from 1851 to 1996. I found the overgeneralization problem caused this.
I developed a new classification method to deal with this problem, but many reviewers and editors told me that even though what you said is correct, we still insist on using SSHS, and your paper can't be published at least in the journals of USA due to common people accepting SSHS. I really don't know why this thing could happen in scientific world, any people know the true reason?
In the response of my last question related to Saffir-simpson Hurricane Scale(SSHS), some people claimed that "Stronger TCs usually have stronger winds but do not always have stronger damage to human and vice versa." I think that he doesn't know OGP problems of SSHS. SSHS use the maximum sustaining winds to stand for the intensity of a tropical cyclone, so there is an overgeneralization problem(OGP), due to the area of the maximum sustaining winds is just very small part of whole area of a tropical cyclone. For example, a person has a big head, but his body is very short, we can not say the man is very strong man. That is the OGP problem!!
Is it funny that some people didn't know this and made a wrong conclusion to
comment on a new classification method for tropical cyclones?
Paterson's Climate Vegetation Productivity (CVP) index is used to quantify potential forest productivity of any region using meteorological factors.
There are models for the structure of hurricane winds (e.g. Holland, 1980, Holland et al., 2010) which are typically applied at the the sea surface for studies of air-sea interaction. We know that in the surface boundary layer, under neutral conditions, Monin-Obikov theory may be applied to find the wind speed as a function of altitude and this is an exponential curve (so called "law of the wall"). Is there any reason that the wind direction might also be a function of altitude? Has the vertical profile of wind direction in a hurricane ever been measured (at a stationary point in the hurricane reference frame)?
I need Tdb and RH% or Tdb and Twb and mostly important : solar intensity . I need them for the purpose of estimating a whole year energy consumption for a new air conditioning system configuration. I wish to find a source for this information in the form of excel sheet table or similar.
I have been observing that when monsoon moisture moves over certain tropical forests located in SE Asia or India, rain clouds with very long streaks form. Has anyone studied if this is caused by Pseudomonas bacteria that live on particular species of tropical trees, and if so which tree species produce the most rain clouds? Attached is a satellite image from August 2014 showing these particular clouds forming over the forests along the SW coast of India.
