Posted: March 9th, 2022

Objective:
• Locate and analyze hurricane data
• Describe the relationship between the pressure and wind speed, and how that affects the hurricane.
Vocabulary:
Altitude – topographic elevation above sea level.
Climate – a geographic area’s pattern of atmospheric or weather conditions over long periods of time, at least 30 years or more.
Latitude – distance from the equator measured in degrees, parallel to the equator.
Longitude- distance from the Prime Meridian in degrees, perpendicular to the equator.
Knot – 1 nautical mile per hour = 1.151 mile per hour.
Weather – local area’s short-term temperature, precipitation, humidity, wind speed, cloud cover, and other physical conditions of the lower atmosphere.
Introduction: A hurricane is a tropical cyclone that originates in an ocean or sea in the equatorial regions and involves heavy rains and a minimum wind speed of 74 mph (119 kh). “Hurricane” is usually used to describe this type of storm over the Atlantic Ocean, whereas “typhoon” is usually used to describe the exact same type of storm in the Pacific Ocean. Before a storm becomes a hurricane, it is a “tropical depression” and then a “tropical storm.”
Classification is determined by wind speed, and when wind speeds reach 74 mph, the storm is then classified as a hurricane. Hurricanes have deepening low-pressure centers that take in moist air and thermal energy from the water’s surface. Convection lifts the air, and as the air continues to rise, it eventually hits high pressure and is pushed outward.
The official Atlantic hurricane season runs from June 1st to November 30th each year. Though tropical systems can form at any time of the year in the tropical Atlantic, they are comparatively rare outside of the official season. The long-term average number of storms for the tropical Atlantic is nearly 10 per year with almost 6 of those becoming hurricanes and 2-3 of those developing into major hurricanes of category 3 or higher on the Saffir-Simpson Scale (Table 4). However, there has been a generally more active period since 1995 with a seasonal average (based on data between 1995 and 2003) of 13 tropical storms, 7.6 hurricanes and 3.6 major hurricanes. September is generally the most active month for the formation of hurricanes in the Atlantic, but this does not preclude large or destructive storms occurring at any time during the season.
