Context:

Two people lost their lives while normalcy was thrown out of gear in Shanghai when Typhoon Bebinca — strongest typhoon to hit China’s financial capital since 1949, made its landfall.

Details

  • Typhoon Bebinca, known in the Philippines as Tropical Storm Ferdie, was a strong tropical cyclone that affected East China, Guam, Philippines and the Ryukyu Islands.
  • Bebinca, a Category 5 typhoon is expected to make landfall along China’s eastern coast at Shanghai.
  • Shanghai last faced a storm of this magnitude in 1949, when Typhoon Gloria struck with similar intensity.

Typhoons

  • Hurricanes and typhoons are the same weather phenomenon: tropical cyclones. 
  • A tropical cyclone is a generic term used by meteorologists to describe a rotating, organized system of clouds and thunderstorms that originates over tropical or subtropical waters and has closed, low-level circulation. 
  • The weakest tropical cyclones are called tropical depressions
  • If a depression intensifies such that its maximum sustained winds reach 39 miles per hour, the tropical cyclone becomes a tropical storm.
  • Once a tropical cyclone reaches maximum sustained winds of 74 miles per hour or higher, it is then classified as a hurricane, typhoon, or tropical cyclone, depending upon where the storm originates in the world.

What is the difference between a typhoon,cyclone,and hurricane?

  • The terms "hurricane" and "typhoon" are regional names for tropical cyclones.
  • Over the Atlantic and East Pacific, tropical cyclones are commonly called ""
  • The common term is "typhoon" for a tropical cyclone that forms in the West Pacific.
  • Tropical cyclones are called just "cyclones" in the Indian Ocean and near Australia.

PRACTICE QUESTION

Q.Consider the following statements:

  1. All tropical cyclones are alike in that they draw heat from warm water at the ocean's surface to power horizontal, rotating wind.
  2. The ingredients for tropical cyclones include a pre-existing weather disturbance, warm tropical oceans, moisture, and relatively light winds.

Which of the above statement/s is/are not correct?

A. 1 only

B. 2 only

C. Both 1 and 2

D. Neither 1 nor 2

Answer: D

Explanation:

Statement 1 is correct

All tropical cyclones are alike in that they draw heat from warm water at the ocean's surface to power horizontal, rotating wind. Although similar in size, tropical cyclones have a different energy source than synoptic cyclones, which are storm systems that draw their energy from weather fronts and jet streams.

Statement 2 is correct

The ingredients for tropical cyclones include a pre-existing weather disturbance, warm tropical oceans, moisture, and relatively light winds. If the right conditions persist long enough, they can combine to produce the violent winds, large waves, torrential rains, and floods we associate with this phenomenon.
