摘要在不同湿度和上升速率条件下，估算了空气中海盐颗粒的凝结量；由此释放的潜热可能是湿气团从海面向云底高度输送的一个重要因素。这些估计值用于计算一系列暂定的温度衰减率，这些温度衰减率可能在暴风雨和海洋空气中的其他条件下在某些上升的湿气团中发现。最后证明，在海洋地区的低层大气中，每公斤空气中加入20至40毫克的精细化海盐颗粒，就会产生足够的热量，引起上升运动，也许还会引起云的形成。
Abstract The amounts of condensation on airborne sea-salt particles are estimated for different humidity and rate-of-rise conditions; the latent heat thereby released may be an important factor in the transport of moist air parcels from neat the sea surface to cloud-base altitudes. These estimates are used to compute a series of tentative temperature lapse-rates which may be found within certain ascending moist air parcels during wind storms and other conditions in marine air. Finally it is demonstrated that the addition of 20 to 40 mg of finely divided sea-salt particles per kg of air to the lower atmosphere in oceanic areas should result in sufficient heating to cause ascending motions and perhaps to cause cloud formation.
