Anticyclonic Circulation Types

Figures 1-9 show mean daily surface level pressure, 500 hPa and 700 hPa charts for each of the anticyclonic Lamb circulation patterns. Table 2 summarises the important characteristics of each circulation type evident in the mean surface level pressure, 500 hPa and 700 hPa charts.
