WEATHER RECORD

In this activity i kept track of the weather for 3 weeks. It seemed like when there was a south wind the temperature was always warmer. For most of the days the sky was cloudy and there was no precipitaion. The baramoter was usually right around 30. It only rained 3 times through out the entire three weeks. The Great Lake levels would drop if it didnt rain that much. When it did rain it only rainned 1/4 of an inch.

ACTIVITY 4

In this activity we learned about how heat affected the temperature of different soils and sands. I learned that soils that are darker get hot faster and can retain heat. The lighter sand reflects the heat and the dark soils absorb it. If their is dark sand alone the Great Lakes the soil will get hotter. The water will evaporate at a faster wait and the water levels wil drop.

El Nino

On April 1st the temperature dropped a lot due to the el nino effect. The ocean temperature effects the weath er patterns and causes the temperature to drop. The temp. drops due to the water temperat1ures of the ocean. The pressure from the ocean currents pushes the hot or cold air across the U.S. The air can carry precipitation to the Great Lakes. The precipitation can cause the Great Lakes levels to rise.

West C

Atmospheric motions is a large-scale movement of air. Atmosheric motions lift and deliver water vapor to high altitudes on the earth. The Great Lake water level can lower when the vapor is lifted from it. Also the water levels could rise if water vapor from another area rained on the great lakes. Wind could carry water from places like the Gulf of Mexico and the the water would end up in the Great Lakes.
