As one of the studies on abnormal refraction over sea surface, made in Sirahama in February, 1959, we have also observed dip of sea horizon under favorable conditions for arising mirage. It is found that the classical linear empirical formula still holds between Th-Tw , h and dip, where Th, Tw and h mean the temperatures at the observer and of surface water, and the observer's height from the sea surface, respectively. The coefficients in the formula are obtained to take rather larger values than usually adopted. Dependence of dip on water vapor is examined and it is regarded to affect dip. It is also found that there exists a strong correlation between Th-To , and Th-Tw, where To is the temperature in the air immediately above the sea surface. A new formula for dip is suggested.Journal
