Tropical Cyclones - Hurricanes Typhoons

This mind map is about tropical cyclones - hurricanes typhoons. Tropical cyclones, often known as typhoons or hurricanes, are among the most dangerous meteorological events. They are severe circular storms that form over warm tropical waters and feature sustained wind speeds of more than 119 kilometers per hour as well as heavy precipitation.

Outline

Tropical Cyclones (Hurricanes & Typhoons)

Weather Systems that develop over warm oceans in the tropics Diameter Range - 150 km to more than 1500 km

Characteristics

Strong winds

Low Central Pressure

Regions Found

Latitude of 8 and 15 degree North & South of equator but not close to equator

Conditions Required

warm waters

presence of Coriolis effect

Coriolis effect: Strong pressure gradient causes air to move straight inwards to the cyclone. However Coriolos effect makes the air to move at angle instead

Northern Hemisphere

Anticlockwise

Souther Hemisphere

Clockwise

Rotary motion of cyclone

Hazards

Storm Surges

Sudden rise of sea level in which water is piled up against a coastline beyond normal conditions at high tide

Massive Flooding

Destroy Property

High Death tolls

Strong Winds

Damage/Destroy infrastructure

injure people

Torrential Rains

Large Amounts of rainfall that cause inland flooding

landslides

remove/crush buildings

destabilise slopes

Impacts

Physical

buildings

bridges

roads

Economic

incomes loss

damaged crops

repair cost

Damaged property

infrastructure

Food shortages

mitigate by food aid

Provision of food and related assistance such as food assistance programmes and subsidies

Social

Disruption

Water supply

Sanitation

Burst Sewage pipes

Contaminate water supplies

Hygience Facilities

disease spread through insects

Displacement of people

Response

Emergency Action

Weather warnings

advisories to make preparations

evacuate people

community cyclone shelters

Mitigation measures

Prediction & Warning

analysing long term climate records

indicate frequency

not accurate

computer modelling

not accurate

Predictions are done at a particular point in time and weather conditions change quickly

Land Use control

Coastal Plain management

Areas along the coast are vulnerable to storm surges

Protected zones

discourage devt by high taxes

Floodplain management

Low Lying area that is near to river or the coast

MasterPlan

reduce potential flood damamge

New devt not prone to flood

evacuation plans

categorization

residents HIGHEST risk

residents HIGH risk

residents MODERATE risk

Effective implementation requires

time

manpower

Reducing vulnerability of infrastructure

buildings resistant to wind and water

protective barriers such as river embankments

utility lines

power

telecommunication

water supply networks

underground

avoid damage by wind / storm surges
