When warmer ocean temperatures prevail, they tend to moderate the air temperature over the island, resulting in milder conditions. This is known as the “ocean-atmosphere temperature interaction” where the warmer ocean surface helps to stabilize the atmosphere, inhibiting the formation of cold fronts and low-pressure systems. In contrast, when the ocean temperatures are colder than average, the air temperature tends to be cooler, making it more susceptible to cold fronts and low-pressure systems.
Formation of Low-Pressure Systems and Cold Fronts
Low-pressure systems and cold fronts are common weather phenomena that occur when there is a significant temperature difference between the warm air near the surface and the cold air aloft. When the Atlantic Ocean temperatures are warmer than normal, they tend to suppress the formation of low-pressure systems and cold fronts over the island. This is because the warmer air is less dense and less prone to rising, which allows the atmosphere to remain more stable.
Subtropical Storms in February
Subtropical storms are a type of storm that forms when a strong low-pressure system develops over warm ocean waters, typically with a temperature of at least 64°F (18°C). When the Atlantic Ocean temperatures are warmer than normal in February, it creates a favorable environment for subtropical storms to form. These storms can bring strong winds, heavy rainfall, and coastal flooding, making them a significant weather event for the island.
