- 13. Tropical Depression A tropicaldepression has a maximum sustained winds of 38 mph or less, and unlike tropical storms and typhoons, tropical depressions are identified with numbers and not names.
- 15. Tropical Storm The maximumsustained surface winds of tropical storms range from 62 to 88 kph. These storms represent an intermediate stage between loosely organized tropical depressions and more intense tropical cyclones, which are also called hurricanes or typhoons in different parts of the globe.

- 38. Storm Surge A stormsurge is a rise in sea level caused by the combination of low atmospheric pressure and high winds, associated with a storm, such as hurricane or typhoon, typically a tropical cyclone. It typically occurs during tropical storms or hurricanes when strong winds push water towards the shore combined with low atmospheric pressure and the rotation of the Earth. It frequently happens along coastal areas and can result in flooding and significant damage to property and infrastructure.
- 39. Storm Surge Storm surgesare primarily caused by the wind and pressure patterns associated with tropical storms and hurricanes. As these storms move over the ocean, they create a mound of water beneath them, which is then pushed ashore by the strong winds circulating around the storm and the low pressure at the center of the storm allows the sea level to rise further.

- 43. Floods Floods are themost frequent type of natural disaster and occur when an overflow of water submerges land that is usually dry. (WHO)
- 44. Types of Floods RiverineFloods Occur when rivers overflow their banks due to heavy rainfall or melting snow. Flash Floods Rapid and intense flooding caused by sudden, heavy rainfall, typically in a short period.
- 45. Coastal Floods Result fromstorm surges, high tides, or tsunamis, causing water to inundate coastal areas. Urban Floods Caused by rapid runoff from impermeable surfaces in urban areas, overwhelming drainage systems. Types of Floods
- 46. Pluvial Floods Result fromexcessive rainfall that leads to surface water accumulation, often in urban settings. Dam or Levee Break Floods Occur when a dam or levee fails, releasing a large volume of water downstream. Types of Floods
- 47. Ice Jam Floods Causedby the accumulation of ice in rivers, obstructing flow and leading to flooding when the ice breaks free. Types of Floods

- 52. Thunderstorms also known asan electrical storm, it is a violent short- lived weather disturbance that is associated with lightning, thunder, dense clouds, heavy rain or hail, and strong gusty winds.
- 53. Thunderstorms Thunderstorms arise whenlayers of warm, moist air rise in a large, swift updraft to cooler regions of the atmosphere. There the moisture contained in the updraft condenses to form towering cumulonimbus clouds and, eventually, precipitation.
- 54. Thunderstorms Lightning discharges occurwhen the accumulated electric charge becomes sufficiently large. Lightning heats the air it passes through so intensely and quickly that shock waves are produced; these shock waves are heard as claps and rolls of thunder. On occasion, severe thunderstorms are accompanied by swirling vortices of air that become concentrated and powerful enough to form tornadoes.
- 55. Thunderstorms Thunderstorms are knownto occur in almost every region of the world, though they are rare in polar regions and infrequent at latitudes higher than 50° N and 50° S. The temperate and tropical regions of the world, therefore, are the most prone to thunderstorms.
- 57. Tornadoes Tornado, a small-diameter columnof violently rotating air developed within a convective cloud and in contact with the ground. (Britannica)
- 59. El Niño The termEl Niño (Spanish for 'the Little Boy') refers to a warming of the ocean surface, or above-average sea surface temperatures, in the central and eastern tropical Pacific Ocean.
- 60. El Niño South Americanfishermen first noticed periods of unusually warm water in the 1600s. During El Niño, trade winds weaken. Warm water is pushed back east, toward the west coast of the Americas. El Niño is the “warm phase” of a larger phenomenon called the El Niño-Southern Oscillation (ENSO).
- 61. El Niño On theother side of the ocean, around South and Central America as the warm water gets pushed away from the coast, it’s replaced by cold water which is pulled up from deeper down in the ocean a process called upwelling. This creates a temperature difference across the tropical Pacific with warmer water piled up in the West and cooler water in the east.

- 65. La Niña La Niñameans Little Girl in Spanish. La Niña is also sometimes called El Viejo, anti- El Niño, or simply "a cold event." La Niña has the opposite effect of El Niño. During La Niña events, trade winds are even stronger than usual, pushing more warm water toward Asia. Off the west coast of the Americas, upwelling increases, bringing cold, nutrient-rich water to the surface.
- 66. La Niña La Niñais caused by an interaction between the Pacific Ocean and the atmosphere above. However, it can have effects on weather all over the world. Also, the environmental conditions during La Niña can lead to more tropical cyclones—which include typhoons —forming in the deep tropics.
