  1. Discussion 3/27 Midterm redux Lectures 14&15 Poster drafts

  2. Oceanography • Water vapor source; hydrological cycle, latent heat, severe weather • Energy exchange w/ atmosphere, ~thermostat • Poleward energy transport

  3. Major Ocean Currents

  4. Upwelling • Also happens off Peru

  5. El Niño

  6. El Niño and La Niña • How does El Niño affect global weather patterns? • Western Pacific experiences less rainfall as warm water moves east. • This shift in rain patterns moves the subtropical jet stream from its normal path. • This change in the path of the sub-tropical Jet allows El Niño to affect the weather and climate of the mid-latitudes as well as the tropics. • The commodities markets use the NOAA El Niño forecasts to influence their buying and selling.

  7. Tropical Cyclones • Hurricanes/Typhoons/Cyclones • Formation: some disturbance gets ‘spun up’ drawing energy from warm ocean waters (T>25oC) • Over 61km/hr, tropical storm, named; over 119km/hr, hurricane • Bands of rising moist air vs. cool, sinking air; particularly in center “eye” • Storm surge, inland flooding, winds • Weaken with cool water, land, or unfavorable airflow aloft
