​Ocean and Weather Patterns

Ms. Pineda

What are the effect of ocean currents, jet streams and distance from large bodies of water on local weather such as air pressure, humidity, precipitation and wind?

​Bell Work

What factors affect weather and climate?​

• Layers of gases surrounding a planet​

​

Atmosphere

• It tends to be more humid in warm climates and near bodies of water.

​

Humidity

Multiple Choice

It tends to be more humid in ______ climates and near bodies of water.

• Cool

• Warm

• Moderate

• Random

• Warmer, tropical climates tend to have higher levels of precipitation.  

Precipitation

Multiple Choice

Warmer, tropical climates tend to have _______ levels of precipitation.  

• Higher

• Lower

• Moderate

• Different

Multiple Choice

Which form of precipitation is produced from a warm atmosphere to a cool surface?

• Rain

• Hail

• Snow

• Sleet

• An air mass is a large body of air (can be cold or warm)

• A front is a boundary separating air masses.​

• ​Cold air masses have a higher air pressure than warm air masses.

• ​When cold air masses meet warm air masses, they push the warm air mass upwards like a wedge and this causes rain.  

​

Air Pressure

• The closer an area to the equator, the warmer the temperature tends to be.

• ​Areas closer to the coast (oceans) tend to have a more moderate temperature. 

• ​Ocean currents can also affect temperature.  

​

Temperature

Multiple Choice

An _________ is a large body of air that travels in one direction due to pressure.

• Front

• Air mass

• Ocean current

• Help describe the position or location of any place on Earth’s surface.

• ​Latitude is the points north and south of the equator.

• Longitude is the points east and west of the prime meridian.

​

Longitude vs Latitude

Multiple Choice

The lines shown in the picture represent ... ?

• Longitude

• Latitude

• The continuous movement of seawater caused by wind, differences in water temperature, salinity, and the gravity of the moon.

  ​

• Warm ocean currents cause warmer climates while cold currents cause colder climates.  

​

​Ocean Currents

​

​How do ocean currents work? - Jennifer Verduin - YouTube

• fast flowing, narrow air currents found in the upper atmosphere or in troposphere of Earth.
