Climatological studies were made simultaneously with the collection of fungi from the air in Kobe-city from February 1966 through February 1967.
Relations between the number of airborne fungal colo nies and various climatic factors (air temperature, humidity, weather, rate of sunshine, wind direction, wind speed, vapour pressure, amount of precipitation and amount of evaporation) or air pollution (suspended particle matter and sulphur dioxide) were studied. It was concluded as follows:
1. The number of colonies was significantly proportional to air temperatur e while slightly less significantly proportional to humidity with a coefficient of correlation,0.81 and 0.59 respectively.
2. The monthly n umber of colonies collected was correlated with monthly amount of precipitation, evaporation and vapour pressure.
3. The number of fungal colonies was in versely proportional to wind speed, i. e., the higher the wind speed, the less the number of fungal colonies.
4. Colonies were large in number on fine and cloudy days; they showed a tendency of decrease in number when it had rained on the previous day or last midnight.
5. Air Pollution with suspended particle matter and sulphur dioxide was proport ional to the number of fungal colonies, i. e., the higher the air pollution, the higher the number of fungal colonies.
