Jun 4, 2020 · Introduction. Cyclones are rapid inward air circulation around a low-pressure area. The air circulates in an anticlockwise direction in the Northern hemisphere and clockwise in the Southern hemisphere. Cyclones are usually accompanied by violent storms and bad weather.
Aug 26, 2023 · Cyclones are centres of low pressure surrounded by closed isobars and having increasing pressure outwards. As air enters an area of low pressure from all directions, the Coriolis Effect bends the direction of the wind to the right of its path.
Nov 28, 2023 · This topic of “Cyclones” is important from the perspective of the UPSC IAS Examination which falls under General Studies Paper 1 (Mains) and General Studies Paper 1 (Preliminary) and particularly in the Geography section of the UPSC Exam.
Aug 26, 2023 · A Cyclone is a system of low level convergence and high level divergence with a rising column of air in the centre of the rotating air mass. If the upper air is not diverging then there cannot be a cyclone present.
Jun 19, 2023 · India escaped the worst of the cyclone’s fury due to early warnings from the India Meteorological Department (IMD) and timely evacuation of people from coastal areas. India’s disaster management system has improved over the years; however, the challenges remain for the future.
Aug 26, 2023 · A tropical cyclone is formed only over warm ocean waters near the equator. Warm, moist air rises up and away from the ocean surface, creating an area of low pressure. It causes the air from surrounding areas with higher pressure to move towards the low-pressure area.
Cyclone: UPSC GS - I Notes. A cyclone is any low-pressure area with winds spiralling inwards. Cyclones rotate anti-clockwise in Northern Hemisphere and rotate clockwise in Southern Hemisphere. The process of Cyclone formation and intensification is called Cyclogenesis.
Aug 31, 2024 · Cyclones are the centers of low pressure. They are surrounded by closed isobars having increasing pressure outward. The wind circulation is from outside towards the central low pressure. They rotate anti-clockwise in the Northern hemisphere and clockwise in the southern hemisphere.
May 8, 2023 · A cyclone is a low-pressure system that forms over warm waters. Mechanism of formation. A high temperature anywhere means the existence of low-pressure air, and a low temperature means high-pressure wind. As air warms over hotter regions it ascends, leading to low pressure at the surface it is covering.
Cyclones and Anticyclones. In meteorology, the term ‘cyclone’ can be defined as the rapid inward circulation of air masses around a low-pressure centre which is circling counter-clockwise in the northern hemisphere and clockwise in the southern.
