A tropical cyclone tracking chart is used by those within hurricane-threatened areas to track tropical cyclones worldwide. In the north Atlantic basin, they are known as hurricane tracking charts . New tropical cyclone information is available at least every six hours in the Northern Hemisphere and at least every twelve hours in the Southern ...
A tropical cyclone is the generic term for a warm-cored, non-frontal synoptic-scale low-pressure system over tropical or subtropical waters around the world. [4] [5] The systems generally have a well-defined center which is surrounded by deep atmospheric convection and a closed wind circulation at the surface. [4]
The strongest cyclone on record in the Bay of Bengal was a super cyclonic storm in 1999, which made landfall on Paradeep, Odisha, in October 1999, with winds of 260 km/h (160 mph). [94] The cyclone killed 9,887 people across Odisha, with 1.6 million houses damaged or destroyed. [96] Damage was estimated at US$1.5 billion. [97]
In 1895, it was noted that cool conditions with unusually high pressure preceded tropical cyclones in the West Indies by several days. Before the early 1900s, most forecasts were done by direct observations at weather stations, which were then relayed to forecast centers via telegraph.
An extratropical cyclone is a synoptic scale low-pressure weather system that does not have tropical characteristics, [33] as it is connected with fronts and horizontal gradients (rather than vertical) in temperature and dew point otherwise known as "baroclinic zones". [34] "Extratropical" is applied to cyclones outside the tropics, in the ...
Constant pressure charts normally contain plotted values of temperature, humidity, wind, and the vertical height above sea level of the pressure surface. [29] They have a variety of uses. In the mountainous terrain of the western United States and Mexican Plateau, the 850 hPa pressure surface can be a more realistic depiction of the weather ...
Severe tropical cyclones defoliate tropical forest canopy trees, remove vines and epiphytes from the trees, break tree crown stems, and cause tree falls. The degree of damage they do along their paths, at a landscape level (i.e. > 10 kilometres (6.2 mi)), can be catastrophic yet variable and patchy. [38]
A "Typhoon" is a tropical cyclone located in the North-west Pacific Ocean which has the most cyclonic activity and storms occur year-round. 2. A "Hurricane" is also a tropical cyclone located at the North Atlantic Ocean or North-east Pacific Ocean which have an average storm activity and storms typically form between May 15 and November 30. 3.
