Which one of the following statements is not correct?

Correct Answer: D. The Monsoon Expedition (Monex) was organized under the joint auspices of the United States of America (U.S.A.) and India.

Explanation: Rainfall variability means the degree to which the amount of rainfall fluctuates from year to year. Mumbai (Western Coast) receives rain (heavy, consistent) mainly from the Southwest Monsoon (June–September) which is around 200–250 cm/year. Due to the Western Ghats, it has less variability which means rains are regular and predictable. Chennai (Eastern Coast) lies in the rain-shadow region during the Southwest Monsoon. It receives most of its rain during the Retreating Monsoon (October–December) from the Northeast Monsoon winds which are comparatively l ess predictable and depend on cyclonic depressions in the Bay of Bengal. During the period of Retreating Monsoon (October to December) , the Southwest Monsoon PYQ’s Solution English 13 withdraws from the Indian subcontinent. The Northeast Monsoon winds blow from the northeast to the southwest direction. These winds pick up moisture from the Bay of Bengal and cause rainfall on the eastern coastal areas — mainly Tamil Nadu, coastal Andhra Pradesh, and southeast coast. Western Disturbances (WDs) are cyclonic disturbances originating in the east of the Mediterranean Sea, travel eastward under the influence of the westerly jet stream and reach northwestern India. When they reach India (mainly Punjab, Haryana, Delhi, western UP, and northern Rajasthan), they cause winter rainfall(Mawath) and snowfall in the Himalayas . These rains are crucial for rabi crops (especially wheat) . The Monsoon Experiment (MONEX) was part of the Global Atmospheric Research Programme (GARP) , organized in 1979 . It was an international scientific study of the Indian summer monsoon . The participants included India , USSR , USA , Japan , Australia , and several other countries . It was organized under the World Meteorological Organization (WMO) and ICSU (International Council of Scientific Unions) .
