An intensity-duration-frequency curve (IDF curve) is a mathematical function that relates the intensity of an event (e.g. rainfall) with its duration and frequency of occurrence. [1] Frequency is the inverse of the probability of occurrence. These curves are commonly used in hydrology for flood forecasting and civil engineering for urban ...
Additional data is received from India's constellation of satellites, such as Kalpana-1, Megha-Tropiques and instruments on board the IRS series and the INSAT series of satellites. [11] Data and observations are also reported into the IMD network from meteorological instruments on board Indian merchant navy and Indian Navy ships. IMD was the ...
Rainfall character is decided by the total amount of rain that has fallen in a set period (usually 1 hour) by counting the number of pulses during that period. Algorithms may be applied to the data as a method of correcting the data for high-intensity rainfall. Tipping bucket rain gauge recorder Closeup of a tipping bucket rain gauge recorder chart
Mumbai recorded 468 mm of rainfall in twelve hours, the highest in a day in August since 1997, according to data from the India Meteorological Department. [5] Transport systems came to a virtual standstill with local trains in Mumbai stationary and various flights cancelled with almost all delayed. On Link Road, a building collapsed.

As proposed in the third five-year plan [2] of India, the Indian Institute of Tropical Meteorology (IITM) was founded as the Institute of Tropical Meteorology on 17 November 1962 at Pune as an individual unit of the India Meteorological Department (IMD), the main organization responsible for meteorological observations, weather forecasts, and detecting earthquakes in India.
However, understanding tropical precipitation is important for weather and climate prediction, as this precipitation contains three-fourths of the energy that drives atmospheric wind circulation. [3] Prior to TRMM, the distribution of rainfall worldwide was known to only a 50% of certainty. [4] The concept for TRMM was first proposed in 1984.
