Cyclonic Circulation Types

Figures 18-26 show mean daily surface level pressure, 500 hPa and 700 hPa charts for each of the cyclonic Lamb circulation patterns. Table 4 summarises the important characteristics of each circulation type evident in the mean surface level pressure, 500 hPa and 700 hPa charts.
