Temporal Variation of Chemical Composition of Rainwater during Individual Precipitation Events

摘要: An automatic sequential precipitation sampler was developed and constructed. It collects rainwater on a volume basis. The sample can be selected for each event due to the minimum analysis. is working since July 80. Analysis includes pH, conductivity, lead, manganese sulphate. In general concentrations of trace elements are high at beginning rainfall, they decrease rapidly remain constant value. For convective showers rainfall intensity show strong inverse relationship. During rain events longer duration, such as warm front precipitations, trends depend synoptic conditions.
