  • Geog 1900: Extreme Weather and Climate

  • Overview I: Extreme weather and climate

  • Our planet earthhttp://www.youtube.com/watch?v=6D5FwFSOJf8

  • The earths climate systemAtmosphereLandOceanSea ice

  • Some basic conceptsAtmosphere: A mixture of gas molecules, microscopically small particles of solid and liquid, and falling precipitationMeteorology: The study of the atmosphere and the processes that form weatherWeather: The state of the atmosphere at a given time and placeClimate: The statistical properties of the atmosphere. (i.e. averages and variability)

  • The mission of the atmospheric sciences is to understand and predict weather, climate, and related disasters

  • Fair weather

  • Monet: Waterlillies (the clouds) 1903

  • Sitting and watching clouds passing

  • Weather-related Disasters: Tropical Cyclones(Hurricanes, Typhoons, Cyclones)

  • Weather-related Disasters: Tropical Cyclones(Hurricanes, Typhoons, Cyclones)Global distribution of the paths of major tropical cyclones during the last 150 years. On average, ~ 80 per year around the world. U.S. Fatalities: normal year 21, Katrina 1836 U.S. Property loss: normal year $5400 million, Katrina $84000 million

  • Weather-related Disasters: Tornadoes

  • Global Occurrence of Tornadoes

  • Weather-related Disasters: Tornadoes U.S. Annual mean fatalities 56, annual mean loss $777 million

  • Weather-related Disasters: Winter Storms

  • Weather-related Disasters: Winter Storms U.S. Annual mean fatalities 57, annual mean loss $329 million

  • Summary: Weather-related Disasters in USHurricanesBlizzards Extreme coldFlooding Lightning FireTornadoesHails

  • Summary: Weather-related Disasters in US

  • Climate-related Disasters over the world Example 1: El Nino

  • Disastrous effects of 1982-1983 El Nino:1.Australia-Drought and devastating brush fires 2.Indonesia, Philippines-Crops fail, starvation follows3.India, Sri Lanka-Drought,fresh water shortages4.Tahiti-6 tropical cyclones5.South America-Fish industry devastated - decrease in nutrients off Peru- fewer fish (anchovy)6.Across the Pacific-Coral reefs die7.Colorado River basin-Flooding, mud slides8.Gulf states-Downpours cause death, property damage9.Peru, Ecuador-Floods, landslides10.Southern Africa-Drought, disease, malnutrition

  • Climate-related Disasters over the world Example 2: Global Warming

  • Global warming is a critical issue we are facing right now

  • Effects on societyHurricane Sandy in 2012http://www.youtube.com/watch?v=KeaG1jRLIBw

  • Weather/Climate and Business- Insurance companiesHistory of Atlantic hurricane activityThe $15 billion insurance loss of Hurricane Andrew in 1992 led to the insolvency of 12 insurance companies and significant market disruption.

  • Climate Change & Economy/Engineering- Green EconomyRenewable energyGreen buildingsClean transportationWater managementWaste managementLand management

  • Weather/climate and International Relationships: Water conflict From The African Water Page Six nations share the watershed of the Mekong, which is affected by unconstrained development, natural droughts, and climate change

  • Climate and History/Politics- Collapse of Maya civilization and Chinese ancient dynasties Droughts

  • Weather/Climate and Basic Science/ Philosophy: Teleconnection and Interaction

  • Climate change and public health- New diseases appear on Tibet and other regions due to higher temperature

  • Weather/Climate and Psychology/Social Work

  • Climate change and EducationPassing the message to the kids

  • SummaryAtmosphere: A mixture of gas molecules, microscopically small particles of solid and liquid, and falling precipitationMeteorology: The study of the atmosphere and the processes that form weatherWeather: The state of the atmosphere at a given time and placeClimate: The statistical properties of the atmosphere. (i.e. averages and variability)Weather- and climate-related disasters: tropical cyclones, tornados, floods, droughts, winter storms, extreme heat, extreme cold, lightning, El Nino, global warmingImpacts of weather/climate on agriculture, business, international relationships, history, science, philosophy, public health, psychology, social work, education,
