Lab 3: Leslie Martinez Part 1: Daily World Weather 1. How many low-pressure centers are shown on this map? - The amount of low-pressure centers that are shown on the map are 25 2. How many high-pressure centers are shown? - The amount of high-pressure centers that are shown on the map are 19 3. How many lows fall into each of the following classes? a. Middle-latitude cyclones - 14 b. Tropical cyclones - 1 c. Weak lows of the equatorial trough (ITCZ) - 10 4. Give the approximate latitude each type of feature is found at - for this you may want to consult another map of the world with latitude lines to cross reference with the provided map above : a. Equatorial trough (ITCZ) - latitude of 5 degrees north b. Subtropical high-pressure cells in the Northern Hemisphere - latitude of 25 degrees north c. Subtropical high-pressure cells in the Southern Hemisphere - latitude of 30 degrees south 5. In which hemisphere ( northern or southern ) are the subtropical high-pressure cells situated at a higher latitude? - Northern Hemisphere 6. Does this world weather map depict Northern Hemisphere summer or Northern Hemisphere winter ? - The world weather map depicts winter northern hemisphere 7. Explain how you can up with your answer for the previous Question 6.
Lab 3: Leslie Martinez - How I came up with my answer for question 6 is when looking at the world weather map it depicts the northern hemisphere winter and this is because the map shows the high pressure. Part 2: NOAA - Tropical Weather - The National Oceanic and Atmospheric Administration (NOAA), National Hurricane Center website is an excellent resource for tracking Atlantic cyclone activity. Take a look at this site, which you can link to here: https://www.nhc.noaa.gov/Links to an external site. Note all the great information you can get from this webpage. - To learn more about tropical weather, let's look at the National Weather Service's JetStream - An Online School for Weather , which you can link to here: https://www.weather.gov/jetstream/Links to an external site. . Now, click on Tropical Weather under "JetStream's Topics" on the right side of the page. Read through this entire lesson, which includes all the subtopics listed on the right side of the page, and answer the questions below. As always, you should paraphrase information on these webpages using your own words, provide answers that are of sufficient length, and avoid quoting! 1. How do warm ocean waters power the development of a hurricane? - Hurricanes can be developed by the evaporation of warm ocean water. If the storm continues to travel the storm will pull in more heat and create moisture, which will give the storm more strength and cause heavier wind and rainfall. 2. What would the category (Saffir-Simpson scale) and name be of an Atlantic hurricane with maximum sustained winds of 160 miles per hour if it was the fourth tropical cyclone of year 2024? - The Atlantic hurricane with the maximum sustained winds of 160 miles per hour in the year 2024 will be a category 5 and will be called hurricane debbie. Similarly, what would the category and name be of an Atlantic hurricane with maximum sustained winds of 100 mph if it was the 23 tropical cyclone of year 2024 (assuming there were that many)? - The Atlantic hurricane with the maximum sustained winds of 100 mph in the year 2024 will be a category 2 and may be called Irma 3. Briefly describe the multiple ways that coastal area flooding can result from a hurricane? - The multiple ways that coastal area flooding can result from a hurricane is by the heavy rains, high waves and waters. 4. What kind of a relation is there between El Nino events and North Atlantic cyclone activity? - El Nino events cause warmer water and cause increased wind. However, El Nino events reduce hurricane activity in the North Atlantic.
