Phenomena/Hurricanes
The determining factor of a storm being called a hurricane, cyclone, or typhoon.
Location
Reason that hurricane seasons occur in different parts of the year in northern and southern hemispheres.
Seasons are opposite, hurricane season is during the warmer parts of year.
Density differences due to changes in temperature and salinity, cause of deep ocean currents.
Thermohaline (density change).
Unit that measures speed/velocity in the ocean (winds, ships, etc)
Knots (kt/nautical mile per hour)
1. Upwelling
2. Downwelling
1. Wind comes from land, brings colder water up along with nutrients to help food chain.
2. Wind from deeper ocean sends warmer water and O2 down deeper in ocean.
1. Year and max strength of Allison.
2. Year of Rita and timeline compared to Katrina and effects it had on Houston area.
1. 2001- Tropical Storm
2. 2005, after Katrina- caused evacuation problems in Houston area.
Current along Texas coastline/in Gulf of Mexico.
Loop current of Gulf Stream
1. Warm currents start and flow to
2. Cold currents start and flow to
1. Equator toward poles
2. Poles toward equator
Gyre meaning and the 5.
Circulation/loops of currents of water:
N. Atlantic
S. Atlantic
N. Pacific
S. Pacific
Indian
Hurricane wind/strength and pressure relationship.
Inverse (higher winds/strength = lower pressure)
Atlantic Hurricane Season duration.
June-November
Current
Huge river in the ocean
Reason that places at same latitudes can have 2 different climates.
Sargasso Sea location and organisms it helps
North Atlantic Gyre, loggerhead sea turtles and American eels.
Cooler water in the Pacific near coast of Peru, and what kind of weather it usually means for us.
La Nina, indicates more dry/drought.
Region (basin) and amount that has the most hurricanes on average (based on our research on 5.2).
West Pacific- 17
Cause of Surface Currents
Wind
Global conveyor belt
Circulates water and nutrients and O2 all over Earth- allowing aquatic life deep in ocean, controls Earth's climate.
Size of Great Pacific Garbage Patch and most common material found.
Twice the size of Texas- plastics
Warmer water in the Pacific ocean near coast of Peru and the kind of weather it usually means for us.
El Nino- indicate more rain for southern U.S.
1. Costliest Hurricane in U.S. history.
2. Ingredients for hurricanes to develop/strengthen.
1. Katrina, 2005
2. Warm sea temperature, warm climate, moisture in atmosphere.
Coriolis Effect
Phenomena that indicates winds blow/turn right (clockwise) in the Northern Hemisphere, and winds blow/turn left (counterclockwise) in Southern Hemisphere.
Gulf Stream info (location, width, climates it moderates, brings to U.S.)
Warm current on eastern U.S. coast, 100 km, moderates U.S. and European climates, brings hurricanes to U.S.
2. Easterlies that blow near the equator.
1. 30-60o
2. Trade Winds
Strong and narrow current that can pull things from the shore.
