Question

distribution pattern of cyclone

Answer 1

Mostly, tropical storms  is formed between the 'tropics', where few develop into 'tropical depressions' but many actually not develop into full 'blown hurricanes' or 'cyclones'.

The majority of storms take place in the late summer to autumn (June to 'November' in the northern hemisphere, 'November-April' in the southern hemisphere) as this is when sea temperatures are at their highest.

The highest number is in the Pacific Ocean, the Atlantic Ocean and Indian Ocean Indian Ocean. The powerful storms take place in the Western Pacific.

EXPLANATION:

Tropical cyclones (TCs) are regional phenomenon. They are classified based on their wind speed

• Tropical Depression: A TC with max constant winds of 38 mph or 33 knots or lesser.  

• Tropical Storm: A TC with max constant winds of 39-73 mph or 34-63 knots  

• Hurricane: A TC with max constant winds of 74 mph or 64 knots or greater. In the "western North-Pacific", hurricanes are called as typhoons and similar storms in South Pacific Ocean and Indian Ocean are called as cyclones.  

• Major Hurricane: A TC with max constant winds of 111 mph or 96 knots or greater,  

The global distribution pattern of TC is summarised as below

• There are about 94 TC globally each year per year. Minimum 4 TCs ensues in December, and the max about 16 TCs in the month of August.

• The western North Pacific has about 27 TCs, the South-Indian Ocean has about 16 TCs, eastern North Pacific has about 15 TCs, North Atlantic has about 10 TCs, South Pacific has about 8 TCs and Australia has about 7 TCs. All these are major TC regions.

• There are regional difference of the month of max numbers of TCs. In the Atlantic, North Indian Ocean, and Pacific the max numbers of TCs happen in September, October, and August respectively. In the South-Indian Ocean, it happens in June. In the Australia and South-Pacific regions, the max numbers of TCs are in March and February respectively.

• The 3 regions, the Bay of Bengal, the South-Indian Ocean, and western North Pacific have TCs in every months. The other regions have a minimum of one TC every free month for the year. For instance, in the North-Atlantic, there is no TC in the month of January.

Answer 2

Answer:

The distribution pattern of cyclones is described as below.

Explanation:

• Cyclone being a large scale air mass is rotates around a low air pressure. Are formed due to Cyclogenesis which is the clash between two distinct front with contrasting air masses.

• Cyclones are found in polar, tropical and temperate zones. The extratropical cyclone develops in the contrast of the low-pressure system to the tropical systems. Formed away from the midlatitudes.

• The tropical cyclone is characterized by the low-pressure centers and is found approx 5° and 30° latitude and generally moves in western directions due to easterly winds. And are formed over moist warm wind patterns.

• They are given different names in different lands they come in contact with. On the eastern Atlantic side of North America, they are called Hurricane and typhoons in Japan,  and willy Willys in Australia. Occurring throughout the May to November season.
