French Southern Territories Barometric Pressure Map

Depending on how many places we monitor in French Southern Territories, the map displays a sampled set of barometric pressure data to give a clear overview of current conditions.

Here you can see which cities experienced the biggest and smallest changes in barometric pressure today. This helps highlight areas with the most stable or unstable weather patterns.

Most volatile

Least volatile

How is it calculated?

Our volatility “beta” number is generated by an algorithm that analyzes hourly barometric pressure changes. It looks at how much the pressure fluctuates from hour to hour. A beta of 0 means no change, perfectly stable pressure. The higher the decimal value, the more variation there has been throughout the day or over a longer period.

Weather Systems

The French Southern Territories are mainly influenced by strong westerly winds called the “Roaring Forties.” These winds bring fast-moving weather systems with frequent storms. Pressure changes quickly as storms arrive and leave, causing sudden shifts between high and low pressure across the islands.

Geography

The geography of these islands is important because they are small, scattered, and surrounded by the ocean. With almost no large mountains or land masses, wind and air pressure are not blocked, allowing storms to pass freely. This leads to more uniform pressure patterns with few sheltered areas.

Seasonal Cycles

Seasonal cycles in air pressure are driven by changes in sunlight between summer and winter. In winter, passing storms are more frequent and pressure drops more often. In summer, the weather is steadier, and high-pressure systems are a bit more common, but storms still occur.

Climate Change

Climate change is making these patterns less predictable. Scientists have noticed the strong winds are shifting south and storms might get stronger. This could bring lower average pressure and more unstable weather in the French Southern Territories in the future.
