The bulk of the rainfall on the Coromandel coast is derived from depressions and cyclones.
Q. Why is difference between duration of day and night hardly felt at Kanyakumari but not?
The day and night are nearly of the same duration at the equator. As Kanyakumari is quite near the equator at 8°4’N the day-night difference is hardly one hour there, and therefore, the duration of day and night is hardly felt at Kanyakumari.
Q. Which month most rainfall receives in India?
Most parts of the country get rainfall during June-September, but on the coastal areas of Tamil Nadu, it rains in the beginning of the winter season. In spite of these differences and variations, the climate of India is monsoonal in rhythm and character.
Q. What type of climate India has?
A tropical rainy climate governs regions persistent to warm or high temperatures, which normally do not fall below 18 °C (64 °F). India hosts two climatic subtypes- tropical monsoon climate, tropical wet and dry climate that fall under this group.
Q. Why is it so hot in India?
El Nino during winters gives India warmer winters and during summers, gives scorched land with low humidity and higher temperatures. On the contrary, La Nina during summer brings an above-normal monsoon in India. Currently, a moderate-intensity La Nina prevails over the Pacific Ocean.
Q. What is India’s climate Class 9?
The climate of India is described as that of the monsoon type. The summer monsoons arising from the Arabian Sea because of their south-west direction strike the Western Ghats first and cause heavy rainfall (about 250 cm). The regions located in the lee ward side of the mountains receive little rainfall.
Q. What is El Nino effect class 9?
EL Nino The periodic development of warm ocean current along the coast of Peru as a temporary replacement of the cold Peruvian current, is called EL-Nino. Features of EL Nino. (i) The presence of the EL-Nino leads to an increase in sea-surface temperatures.
Q. What is Southern Oscillation Class 9 Ncert?
Generally, when the tropical eastern south Pacific Ocean experiences high pressure, the tropical eastern Indian Ocean experiences low pressure. It is this periodic change in pressure conditions which is known as the Southern Oscillation or SO.
Q. What is called Southern Oscillation?
El Niño and the Southern Oscillation, also known as ENSO is a periodic fluctuation in sea surface temperature (El Niño) and the air pressure of the overlying atmosphere (Southern Oscillation) across the equatorial Pacific Ocean. The Southern Oscillation describes a bimodal. variation in sea level barometric pressure.
Q. What is full form of ENSO?
The El Niño-Southern Oscillation (ENSO) is a recurring climate pattern involving changes in the temperature of waters in the central and eastern tropical Pacific Ocean.
Q. Why is El Nino called Southern Oscillation?
The Southern Oscillation is the atmospheric component of El Niño. This component is an oscillation in surface air pressure between the tropical eastern and the western Pacific Ocean waters. El Niño episodes have negative SOI, meaning there is lower pressure over Tahiti and higher pressure in Darwin.
Q. What are some negative effects of El Nino?
Severe drought and associated food insecurity, flooding, rains, and temperature rises due to El Niño are causing a wide range of health problems, including disease outbreaks, malnutrition, heat stress and respiratory diseases.
