IMD became a member of the World Meteorological Organisation after independence on 27 April 1949. [6] The agency has gained in prominence due to the significance of the monsoon rains on Indian agriculture. It plays a vital role in preparing the annual monsoon forecast, as well as in tracking the progress of the monsoon across India every season ...
In 2003, IMD substantially changed its forecast methodology, model, [44] and administration. [45] A sixteen-parameter monsoon forecasting model used since 1988 was replaced in 2003. [ 44 ] However, following the 2009 drought in India (worst since 1972), [ 46 ] The department decided in 2010 that it needed to develop an "indigenous model" [ 47 ...
The ENIAC main control panel at the Moore School of Electrical Engineering operated by Betty Jennings and Frances Bilas. The history of numerical weather prediction began in the 1920s through the efforts of Lewis Fry Richardson, who used procedures originally developed by Vilhelm Bjerknes [1] to produce by hand a six-hour forecast for the state of the atmosphere over two points in central ...
The storm produced heavy rainfall in southeastern Bangladesh. [10] Seven people were killed by landslides in Cox's Bazar District.. [10] Rainfall flooded some 200 villages in Cox's Bazar Sadar. Six other upazilas remained flooded. In Ukhia Upazila, flooding affected over 50,000 people across 40 villages. Among them were the Haldia Palong and ...
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.
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 ...
The next day, the IMD noted that a low-pressure area had formed adjacent to the cyclonic circulation. [5] Late on 23 May, the IMD upgraded the system into a well-marked low, stating that it was rapidly coalescing. [6] The next day, the IMD stated that the depression formed in the Bay of Bengal, designating it as BOB 01. [7]
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.
