(ii) High relative humidity of the atmosphere to a height of above 7,000 m facilitates condensation of water vapour into water droplets and clouds, releases heat energy thereby inducing a drop in pressure. Tropical cyclone formation is influenced by many factors, but the role of warm sea-surface temperatures as the primary source of energy for cyclones is paramountxxvii. At low altitudes, air comes from the converging cyclonic flow, humidified by evaporation from the ocean surface. Nivar, currently over southwest Bay of Bengal, is moving west-northwestward at a speed of 11kmph. Explanation: Tropical disturbance, tropical depression, tropical storm, and full-fledged tropical cyclone. Lastly, tropical cyclones eventually decay, mostly due to the loss of an energy source, which is usually the oceans warm surface. Sometimes, the eye disappears as it approaches the island, and reappears a few hours later, several tens of kilometres in the wake of the obstacle. There needs to be an area of enhanced thunderstorm activity which can act as a focus for the development of the cyclone in the presence of all the other conditions listed above. Cyclone Nivar - Wikipedia widgets-close-button - BYJUS This storm led to an estimated 1800 deaths mostly through disease and dehydration in the days following the storm. How to discuss the stage of development of the tropical cyclone - Quora The change in the distribution of storm activity temporarily disrupts the cyclones dynamics. The weak compensatory downward movement in the eye heats the air by compression and maintains the central hot anomaly. This effect leads to a temporary decrease in the intensity of the cyclone when the Eyewall progressively dissipates, before a new intensification when the external bands have gradually organized themselves into a new Eyewall. Hurricanes reaching Category 3 and higher are considered major hurricanes because of their potential for significant loss of life and damage. One of the conditions needed for a tropical cyclone to develop is a pre-existing near-surface disturbance, low-pressure area or region of convergence. When storms move into larger vertical wind speed environments, or areas with low sea temperatures, dry conditions or other changes in wind speeds, the storms can break up. At a Glance.
