Cyclone Fengal
Cyclonic Storm Fengal (; ) was a deadly tropical cyclone that brought significant flooding and damage to Southern India and Sri Lanka. The fourth and final cyclonic storm of the 2024 North Indian Ocean cyclone season, Fengal originated from a tropical disturbance off the coast of Sumatra, Indonesia on 14 November. It killed at least 37 people; 20 in India and 17 in Sri Lanka, along with 20 injuries. Economic losses reached $55 million. Meteorological history On 14 November, the Australian Bureau of Meteorology noted the potential formation of a tropical low west of Sumatra, Indonesia. The tropical low formed a few days later due to the occurrence of a westerly wind burst. As the low formed, it led to the formation of an invest on 18 November, designated as 96S by the JTWC. It later formed a deadly twin cyclone. Another invest was formed on 21 November, designated as 99B. This invest struggled to develop initially due to the presence of strong wind shear with convection spread ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern India
South India, also known as Southern India or Peninsular India, is the southern part of the Deccan Peninsula in India encompassing the states of Andhra Pradesh, Karnataka, Kerala, Tamil Nadu and Telangana as well as the union territories of Lakshadweep and Puducherry, occupying 19.31% of India's area () and 20% of India's population.

Cyclone Robyn (2024)
Tropical Cyclone Robyn was a deadly and erratic tropical cyclone that contributed towards heavy rains and flooding throughout the Indonesian islands of Sumatra and Java in November 2024. Robyn was the first tropical system to form during the 2024–25 Australian region cyclone season. Meteorological history By early November 2024, a moderately active Madden-Julian Oscillation (MJO) moved eastwards into the Indian Ocean, aligning with an equatorial Rossby wave. On 14 November, the Australian Bureau of Meteorology (BoM) noted that a tropical low could may form to the west of Sumatra, Indonesia, and pre-designated it as 01U. This came into fruition 9 days later, when both the BoM and the United States Joint Typhoon Warning Center (JTWC) reported that the system had formed approximately to the northwest of Cocos (Keeling) Islands, aided by a westerly wind burst that also contributed to the formation of Cyclone Fengal. Moving generally to the southeast, the low struggled to organi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tropical Cyclone Formation Alert
A Tropical Cyclone Formation Alert (TCFA) is a bulletin released by the U.S. Navy-operated Joint Typhoon Warning Center in Honolulu, Hawaii or the Fleet Weather Center in Norfolk, Virginia, warning of the possibility of a tropical cyclone forming from a tropical disturbance that has been monitored. Such alerts are generally always issued when it is fairly certain that a tropical cyclone will form and are not always released before cyclogenesis, particularly if the cyclone appears suddenly. The TCFA consists of several different checks that are performed by the on-duty meteorologist of the system and its surroundings. If the condition being checked is met, a certain number of points are given to the system. Parts of the TCFA Section 1 The first section of the TCFA contains information on the area of the alert as well as the estimated center of the circulation. The estimated maximum sustained winds are provided as well. Section 2 The second section generally contains more specif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Depression (weather)
In meteorology, a low-pressure area (LPA), low area or low is a region where the atmospheric pressure is lower than that of surrounding locations. It is the opposite of a high-pressure area. Low-pressure areas are commonly associated with inclement weather (such as cloudy, windy, with possible rain or storms), while high-pressure areas are associated with lighter winds and clear skies. Winds circle anti-clockwise around lows in the northern hemisphere, and clockwise in the southern hemisphere, due to opposing Coriolis forces. Low-pressure systems form under areas of wind divergence that occur in the upper levels of the atmosphere (aloft). The formation process of a low-pressure area is known as cyclogenesis. In meteorology, atmospheric divergence aloft occurs in two kinds of places: * The first is in the area on the east side of upper troughs, which form half of a Rossby wave within the Westerlies (a trough with large wavelength that extends through the troposphere). * A s ...

Tropical Cyclogenesis
Tropical cyclogenesis is the development and strengthening of a tropical cyclone in the atmosphere. The mechanisms through which tropics, tropical cyclogenesis occur are distinctly different from those through which temperate cyclogenesis occurs. Tropical cyclogenesis involves the development of a warm core, warm-core cyclone, due to significant convection in a favorable atmospheric environment. Tropical cyclogenesis requires six main factors: sufficiently warm sea surface temperatures (at least ), atmospheric instability, high humidity in the lower to middle levels of the troposphere, enough Coriolis force to develop a low-pressure area, low-pressure center, a pre-existing low-level focus or disturbance, and low vertical wind shear. Tropical cyclones tend to develop during the summer, but have been noted in nearly every month in tropical cyclone basins, most basins. Climate cycles such as ENSO and the Madden–Julian oscillation modulate the timing and frequency of tropical c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
