Question

Weather impacts of cyclones

Answer 1

High winds Produce high winds over 119 km/h Can cause severe damage to buildings. Trees can be uprooted by the force of he wind , smaller constructions such as beach huts can be moved or destroyed. Can cause damage , injury or loss of life Intense Rainfall As tropical rainfalls move over the ocean they take up a larg amount of water this results in a large volume of rainfall Wether forecasters can estimate how much rain based on how fast the storm has been treavelling over the water. The internse rainfall created by the cyclone can lead to flooding, damage, injury (fast flowing water can knock people over) Storm surges Large rea of low pressure , causes level of sea to rise

Answer 2

In areas near equator water is heated to 26.5ºC-27ºC evaporates rises into atmosphere Rising air forms an area of low pressure , which when winds converge at the ocean Belgians to grow bigger and more powerful The rising air begin to rotate due to the coriolos effect(effect of earth spinning) This creates a tropical cyclone As the cyclone routes annd grows it begins to move over the ocean as it moves it picks up more evaporated water remaking it more powerful In the northern hem they move westwards i n S hem eastwards Severe cyclones causes huge damage when they reach land they are an avgof 12 severe cyclones annually

Answer 3

Category 3 cyclone Then cat 1 when hit land Peaked as hit cuba Happened 24th October in Jamaica hit New Jersey lost energy and disappeared in Ohio on nov 2nd Impacts Social- 150 people died- most of any hurricane e since Katrina Milllions without electricity or water Schools were distrusted for day Economic New York marathon cancelled , reducing money from tourism Total economic damage was 65 billion New York stock exchange was closed for days- making economy Lots of businesses were damaged through high winds Environmental Nature reserves for animals were flooded by the storm surge, causing damage Raw sewage. Released into waters in New York due to coastal flooding Responses GOVT- Voted to provide Ben of dollars to help with rebuilding and supporting victims Rebuilding-The money provided by GOVT was split some went to homeowners and people worst hit by hurricane to rebuild their lives some went to businesses and community Modern Technoogy - one of first hurricanes which used modern technology to aid responses Social media warnings Relief efforts- American Red Cross and US Army help with supplie giving to victims

Answer 4

Hit land in Philippines on 7th nov 2013 Winds over 306 km/h Passed over Philippine’s by 8th and carried on path west towards south east chia Formed on 2nd nov 2013 of South Pacific Ocean near Micronesia and travelled towards Philippines Impacts Social 6000 deaths with thousands reported missing AID Couldn’t reach vulnerable people due to landslides blocking etc Electricity was cut off to affected isnaldns due to flooding and landslides Economic $2 Ben in damages Foreign AID agencies attempted to provide economic AID to vulnerable people Environmental Coastal areas of mangrove swamps were damaged and uprooted Oil spill due to an oil tanker crashing damaging environment Several areas evacuated due to chemical leaks Response Seven provinces in Philippines were placed under state of national clmatiy - allowed govt to redirect funds to help address the problems created by the typhoon Relief efforts was slowed considerably because of damage to infrastructur Air port severely damaged

Answer 5

Ocean current - currents that distribute and spread warm water and cold water around world An darea recieve it cold water likely to recieve drought El Niño Air and water currents in the Pacific Ocean usually flow in one direction. El Niño events happens when these currents get weaker or change direction. What is El Niño? Trade winds Low Pressure El Niño events happen when these currents blowing westwards get weakt or change direction (and go eastwards). If pressure in the wester Pacific increases and pressure in the eastern Pacific decreases, then the air and water currents can change from westerlies to easterlies. El Nino leads to less rainfall, less flooding, and more drought in the West (Australia). El Niño leads to more rainfall and flooding in the East (Latin America). La Niña When air and water currents strengthen All together usually in the pacific, there i an area of low pressure over the western Pacific Ocean and an Arab of high pressure over the Easter Pacific Ocean These conditions result in trade winds blowing wet i over the pacific form s America to Australia Depressions of rain Areas of high pressure can block depression stripping rain from reaching an area Main cause of drought is air falling Hydrological causes When rivers drive ttc usually caused by lack of rainfall Jet streams Fast flowing air current that push weather around world Can cause droughts by pushing high pressure air to different regions - ai sinks = no evaporation= no dorought METEROLGICA; WHEN AN area receives less rainfall and precipitation for an extende period

Answer 6

Droughts are periods of time with below-average amounts of rainfall. Wat supplies run low or run out during droughts. Drought is caused by a lack of rainfall.

Answer 7

2012 - preset California is located in the South-west of the USA. It borders many other states including Oregon, Nevada and are one Richest US state Causes Natural-precious of lower rianladd due to high pressure e Very Lowe snowfall in mount as which melt and add to rivers usually that didnt happen s Human- Colorado rivers supplies with water also supplies 6 other states . Stars had overextracted water form tge river California has over extracted water from rivers Impacts Social Ash from wildfire cintimnaetd water supplies Buildings tated to subside due to water form underground aquifers being ver extracted \ Reduced waterline. Reduced ammount of hydroelectric energy Economic COS farmers 1.8 by + 10,000 agricultural jobs have been lost Environmental Wildfires have destroyed large ares of land in California Less rainfall more water is taken from rivers this impacts w8dife living there Responses Monitoring rivers to check fish species hadn’t been endangered River floes were limited during winter months to yield up reservoir behind da Warnings on limiting water usage Control points to check wate rhadt been contaminated by shaky seawater Education progmraaaes to show people how to use water

Answer 8

Ethiopia is located in the East of Africa. IIt borders many other countries, including Somalia, Kenya and Sudan. It is also near to the blue Nile and lake tana+Red Sea Causes Natural- rely on two periods of rain a short and long wet season Since 1980s short season of rain has been much shorter Longseason ebcomes unpredictable Human causes- warmer inane temp caused by inmate temp pushing diet air towards Ethiopia Impacts 85% of Ethiopians live in countryside and rally on agricultur. Farming was negatively impacted Widespread famine Has occurred ad not enough food can be grown People had to ingrate away Economic Cost $1.66 bn Environmental;n 4.5 million animals have died Forest fires Responses Farmer being helped ling term- development in tech and starter guides that are more resistant to drought NGOSs are working to provide long term aid, such as clean water supplies , food and medial care OXFAM UNICEF Organise own relief programmes BAND AID RELAEASED THE DIGLE DO THEY KO ITS CHRISMTAS TIME TO RSISR MONEY
