Instructions: Use the resources embedded in or attached to adorngeo to complete the following tasks.

Part 1: FormationFormation Stages

Using the images above and the following links, the textbook, and support links at the bottom of the worksheet, summarize the steps it takes to form a hurricane. Add your own hand drawn annotated images to the descriptions for step-by-step formation of a hurricane (take photos and upload them). Make sure you use these key terms… warm water, low pressure, warm air sucked upwards, pulling drier cooler air, warm moist air, storm surge, strong winds.https://www.bbc.com/bitesize/guides/zpxgk7h/revision/1(https://www.bbc.com/bitesize/guides/z37wrdm/revision/1)https://www.vox.com/science-and-health/2016/10/6/13191010/how-hurricanes-form-tropical-storms-guide

Step 1 The warm air from thunderstorms and the deep warm ocean surface (greater than 27 C

Step 2 Trade winds at the equator cause the storm to spin due to the earth’s rotation and Coriolis

Step 3 Air continues to rise and the pressure starts to decrease at higher altitudes.

degrees) mix together and start to rise to create low pressure.

effect.

Step 4 Air rises faster and draws in more warm air from the sea surface while also sucking cooler air downwards.

Step 5 As the storm moves over the ocean, it picks up more warm moist air. The speed of its winds increases as more air is sucked in.

Step 6 It can take hours or days to fully form the wind speeds officially termed a hurricane. The eye has calm winds which are surrounded by a spinning vortex of high winds and heavy rain.

Formation- Measuring a Hurricane

The Saffir-Simpson Index is one of the most popular measuring tools to categorize hurricanes/typhoons based on their wind speeds. It is expected you can understand the key stages and differences of steps of formation and wind strength between tropical depressions, tropical storms, and hurricanes.

Part 2: Distribution

Using this map summarize the distribution of hurricanes, cyclones, and typhoons. What is the difference between them the different terms?

Using this map explain why the seasons for hurricanes, cyclones, and typhoons are different worldwide. *HINT: Consider climate, weather, and seasons.

Part 3: Effects of Hurricanes and Storm Surges- GeneralSummarise the key effects of a storm surge from hurricanes on coastlines and coastal communities

Summarise the key effects of the powerful winds from hurricanes on coastlines and coastal communities

Summarise the key effects of the heavy rains hurricanes can bring
