We present an analysis of the impact of circulation weather types (CT) on a factor that might influence biological systems and the human condition, the electric state of the atmosphere. We present results on the influence of CT to the magnitude, the direction (positive or negative), the fluctuation magnitude, and the short-term peaks of the atmospheric electric field (potential gradient, PG), using data from a station in Greece. CTs with high vorticity centers over Greece are associated with high positive and negative excursions of the PG, higher PG variability, and rain events. CTs with thinner 850–500 hPa layer are associated with higher daily mean values of fair-weather PG. We also examine the influence of CT on the frequency and amplitude of the naturally occurring extremely low-frequency electric field fluctuations known as Schumann resonances (SR) using data from a station in Hungary. The first and second mode SR frequencies are increased during CTs associated with higher 500 hPa geopotential heights and higher 850–500 hPa layer thickness. This hints to a lower-upper atmosphere coupling. So, CTs not only influence the general temperature and humidity conditions to which the biosphere is exposed, but they also affect its exposure to atmospheric electric fields.

环流天气类型对生物圈暴露于大气电场的影响

我们分析了环流天气类型 (CT) 对可能影响生物系统和人类状况、大气电状态的因素的影响。我们使用希腊一个台站的数据，展示了 CT 对大气电场的幅度、方向（正或负）、波动幅度和短期峰值（电位梯度，PG）的影响的结果。在希腊上空具有高涡度中心的 CT 与 PG 的高正负偏移、更高的 PG 变异性和降雨事件有关。具有较薄 850-500 hPa 层的 CT 与较高的晴天 PG 日平均值相关。我们还使用匈牙利一个站的数据检查 CT 对自然发生的极低频电场波动的频率和幅度的影响，称为舒曼共振 (SR)。在与更高的 500 hPa 位势高度和更高的 850-500 hPa 层厚度相关的 CT 期间，第一和第二模式 SR 频率增加。这暗示了低层大气耦合。因此，CT 不仅会影响生物圈所处的一般温度和湿度条件，还会影响其暴露于大气电场中。
