Geopotential height

On this page, we present the results of the 500hPa geopotential height. Geopotential height represents the height in the atmosphere where the pressure is at 500hPa. It is a crucial parameter that helps us understand and describe the flow behavior in the atmosphere, including wind speeds and directions. These factors play a significant role in driving extreme temperature events. By analyzing the geopotential height, we gain insights into the atmospheric conditions that contribute to the occurrence of extreme temperatures.

 


Mean Z500 anomaly and mean values during the 50 CENA

 

Figure 1: 500hPa Geopotential height anomaly (Z500, in m) during the 50 CENA events at different time lags. Panel a) anomalies at lag -5, panel b) at lag 0, and panel c) at lag +5. Panels d,e and f shows the mean Z500 values at lag -5,0 and +5. The white dashed contour lines in panels a,b and c shows the Z500 anomaly each 20 meters. Brown lines in d,e,f connects areas of same Z500 height. Areas with statistically significant negative anomalies are indicated by the symbol ““, while statistically significant positive anomalies are indicated by ““.
