| Abstract: | Summer-time rainfalls during 1980 and 1981 were collected at several sites near La Grande, 200 km inland from the James Bay coast, in Northern Quebec. These were analyzed for pH and the concentrations of major ions. Concurrent and prior measurements were also taken or derived for a series of meteorological parameters including 85 Kp level wind speed and direction, 85 Kp level air temperature, vertical air movement, these during and prior to rainfall, precipitation amount, duration and intensity, prior duration of precipitation, precipitation type, boundary layer height, surface pressure and surface pressure change and atmospheric divergence.Results demonstrate that wind speed at 85 Kp level 48–72 h prior to rainfall, wind direction at 85 Kp 72 h prior, air temperature at 85 Kp during rainfall and 60–72 h prior, vertical movement of the atmosphere 24 h prior, boundary layer height, surface pressure and surface pressure change and rainfall amount and duration at the site as well as prior duration of rainfall consistently correlate with the log10 of major ions in rainfall. Also surface wind direction, precipitation type and the trajectory of air masses do not consistently relate to the pH of rainfall. |
