The Properties of Air Masses over Batavia

[摘要] From the excellent Verbandelingen(1) of the Batavia Observatory we worked out for dry season (May-Oct) and rainy season (Nov.-April) separately, as seasonal variations may affect the values of characteristic properties of air masses to a considerable extent. In table 1 only readings taken during ascent at intervals of every 1km above M. S. L. have been included. We found that during the passage of the air from Batavia to Nanking(2), Hong Kong(3) or Manila(4), there are definite increases in temperature and humidity at all heights above the surface. These results indicate that while over China Sea or Sea to South of Japan the air is warmed at the surface, resulting in strong convection and thorough mixing.
