French Guiana Barometric Pressure Map
Depending on how many places we monitor in French Guiana, the map displays a sampled set of barometric pressure data to give a clear overview of current conditions.Trends Today
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
French Guiana’s air pressure is shaped by weather systems like the Intertropical Convergence Zone (ITCZ). The ITCZ is a belt of clouds near the equator where northeast and southeast trade winds meet, causing lots of rising air and low pressure. Its position shifts north and south during the year.
Geography
Geography also affects pressure in French Guiana. The region is flat and close to the Atlantic Ocean, so moist ocean winds easily reach the land. Forests and rivers have little impact on air pressure compared to mountains, which French Guiana does not have.
Seasonal Cycles
Seasonal cycles cause pressure to change. From December to July, the ITCZ moves over French Guiana, bringing rain and lower pressure. In August to November, drier air and more stable high pressure return as the ITCZ moves away, leading to less rain and hotter days.
Climate Change
Climate change may affect air pressure patterns by changing rain cycles and shifting the ITCZ’s position. This could lead to longer or harsher rainy and dry seasons, with stronger or longer-lasting periods of low or high pressure.
