Unit 8.5 B Weather
air masses and how they interact. Impact of elevation and lakes on Michigan.
Question | Answer |
---|---|
When a cool air mass pushes a warm air mass upward, the warm air cools and? | condenses, water vapor and clouds then form. |
How does thermal energy transfer differently from land and water? | Thermal energy flows from areas of high temperatures to areas of low temperatures. Thermal energy flows from the warm water through the air to the cooler land. |
Air masses that form over warm bodies of water would be? | Warm in temperature and high in humidity. |
Which location of the mountain range forms clouds and rain? | Windward side or the side closest to the water. |
What happens to the warm air as it rises over the mountain? | It cools |
This area is created due to little to no rainfall | Rain shadow |
Michigan and its surroundings is a system. When creating a weather model the components scientists should use are | Great Lakes, the atmosphere, and topography. |
If a scientist is creating a weather model for Michigan the processes they should consider are | air masses interacting that might cause storms, elevation changes that could impact precipitation, and large bodies of water impact. |
If a weather model of Michigan was created, what application would you expect the model to be used for | predicting snowfall patterns, show how mountains cause rain shadows, or show temperature patterns in various areas. |
The weather pattern expected when two air masses interact | clouds and possibly precipitation. |
Explain the process that occurs when two air masses interact | regions of high air pressure move towards regions of low pressure, pushing the low pressure air up into the atmosphere where it cools, water vapor condenses to form clouds. Precipitation is possible. |
Weather data that scientist may use to predict weather | wind speed, temperature, wind direction, air pressure, humidity, rain/snow amounts. |
Weather forecast will never be anything more than a prediction | because there are many things that can affect the weather, the atmosphere can change making it difficult to get any kind of guarantee when it comes to predicting the weather. |
As air masses rise to higher elevation | the air masses temperature lowers, the higher the elevation the lower the temperature of the air mass. |
Rain shadows are created due to | the air mass sinking causing the air to get warmer, any condensed water evaporates into water vapor, the clouds disappear and there is no more precipitation. |
When the air mass encounters a mountain range | it is pushed up and over the mountain. As it moves higher, the air mass cools and water vapor within the air mass condenses to from clouds and produces precipitation. |
