Transcription

1 ` Weather FActors P: Analyze weather Q: What are the factors that cause weather? May 8 4:15 PM Analyzing AIR MASSES & THEIR MOVEMENT Read and take notes... Using pages 72-79: (IN YOUR JOURNAL!) - Identify the four types of air masses (use diagram on p.74) - Contrast the four types of fronts * Draw a diagram of each * Describe the type of weather associated with each - Contrast cyclones and anticyclones - Explain the difference between high & low pressure systems (H & L on weather map) see p. 79 LOL Assessment (p. 79) #1abc, 2abc, 3abc ` Oct 18 8:05 AM 1

2 Predicting Weather P: Analyze weather maps Q: What factors are considered when forecasting weather? Nov 8 3:48 PM Predicting Weather Use the Weather Map on p. 97 to list the symbol that represents each of the following: warm front cold front stationary front occluded front High pressure system Low pressure system precipitation (snow, rain, drizzle, etc) Complete the Skills Lab on p Read & complete the procedure - Answer Analyze and Conclude questions #1-7 Nov 7 3:50 PM 2

3 Use the Weather Map on p. 97 to list the symbol that represents each of the following: warm front cold front Predicting Weather stationary front Weather Wizard FRONTS occluded front High pressure system Low pressure system precipitation (snow, rain, drizzle, etc) Nov 7 3:50 PM Different Fronts Cold Fronts Go to active art! fast moving COLD air mass overtakes WARM air mass cause abrupt weather changes associated with strong winds and severe thunderstorms followed by cold, dry weather Warm Fronts WARM air mass overtakes a slow-moving COLD air mass often bring clouds, light rain or storms followed by warm and humid weather Stationary Fronts COLD and WARM air masses meet at a "stand-off" rain, snow, fog can form where the air meets brings many days of clouds or precipitation Occluded Front Fronts a WARM air mass gets caught between two COOLER air masses temperature near the ground becomes cooler weather may become cloudy, rainy or snowy Nov 4 9:49 AM 3

4 Skills Lab - page 99 # Highest temperatures are represented in orange, and light purple represents the lowest temperatures. 2. Highest = Miami; Lowest = Billings 3. Rain - parts of California, Texas, & nearby states Snow - parts of the Northwest 4. Three fronts = warm, cold & stationary 5. Low pressure = 2; High pressure = 2 6. Probably winter - temps are fairly low 7. Minneapolis = a cold front approaching; clouds & snow predicted, then cold, dry weather Nov 14 10:35 AM Predicting Weather - More to Explore 1. Analyze a current weather map of the US and compare it to the map shown on p What things are similar? What things are different? 3. Predict some factors that you think affect the weather. May 8 4:27 PM 4

5 Weather Around the United States Research the weather in the following cities: 1--St. Louis, MO 2--Knoxville, TN 3--Miami, FL 4--New Orleans, LA 5--Brownsville, TX 6--Milwaukee, WI 7--Des Moines, IA 8--Buffalo, NY 9--Charleston, SC 10--Seattle, WA 11--Phoenix, AZ 12--Bangor, ME May 8 4:30 PM City Investigation Using your map and research to find the answers to these questions. Write the information for each city in your journal. 1. Where is the city located? (northwest, south, etc.) 2. What is the current temperature? 3. What do the current skies look like? (sunny, cloudy, etc.) 4. Is there any precipitation predicted? What kind? 5. What major land features are near the city? 6. What is the weather predicted to be for the next 5 days (5 day forecast). May 8 4:39 PM 5

6 MAKE PREDICTIONS: Look back at the US weather map. - Analyze what you see compared to the forecast in your city. - What do the symbols you see represent? - How does this relate to the weather predicted? - What will look different (if anything) about the US map near your city later in the week? May 8 8:34 PM Presenting City Weather Information During your presentation explain: - Location and nearby landforms - Day 1 weather (temp, precipitation, cloud cover, etc.) - 5 day weather forecast - Your predicted US weather map based on your city's 5 day forecast May 8 8:44 PM 6

7 LOL - Conclusions After listening to the presentations... 1.) What do you notice about the weather across the country? List some trends that you observed. 2.) Based on what you can observe from the various cities, what factors contribute to the weather in a given area? 3.) What is the biggest factor that contributes to weather in a given area? 4.) How do land features (e.g. mountains, elevation, proximity to water, etc.) contribute/affect weather? Let's Investigate! May 10 10:32 AM Latitude Search P: Analyze the effect of latitude on weather Q: How does the weather of cities with similar latitudes compare? Oct 31 8:33 AM 7

8 Create the following data table: Latitude Search City Location Temperature Precipitation Cloud Cover Land Features 1.) 2.) 3.) 4.) 5.) Fill in the chart with information about 5 cities with the SAME LATITUDE as the city you researched. (3 of the cities can be from the US. The other 2 need to be from other countries around the world.) May 11 6:10 PM Find Another St. Louis May 11 7:10 PM 8
