There are several factors that can cause hurricanes to increase in strength:
1. Warm Ocean Waters: Hurricanes are fueled by warm ocean waters, typically above 80°F (27°C). Warm waters provide the energy needed for the storm to intensify by evaporating moisture and generating strong convection.
2. Low Vertical Wind Shear: For a hurricane to strengthen, it requires a low vertical wind shear, which means winds at different altitudes should not vary significantly in direction or speed. This allows the storm to maintain its structure and develop a well-defined circulation.
3. Moisture and Humidity: Moisture-rich environments provide ample fuel for hurricanes to intensify. High levels of moisture in the atmosphere lead to the formation of deep convection and heavy rainfall, contributing to the growth of the storm.
4. Coriolis Effect: The Coriolis effect, caused by the rotation of the Earth, plays a role in hurricane formation and intensification. As the storm develops and spins counterclockwise in the Northern Hemisphere (clockwise in the Southern Hemisphere), the Coriolis effect helps in sustaining the storm's rotation and increasing its strength.
5. Favorable Atmospheric Conditions: A combination of factors, including high humidity, unstable air masses, and low-pressure systems, create an environment conducive to hurricane development. Storms can strengthen when they encounter these favorable atmospheric conditions.
It is important to note that climate change can potentially impact hurricane strength and frequency. Warmer ocean temperatures due to global warming can provide more energy for storms to intensify, potentially leading to more intense hurricanes in the future.
