GENERAL FEATURES 
GRADUAL DECREASE OF AIR PRESSURE AND PROMINENCE 
OF SEMIDIURNAL OSCILLATION; GRADUAL RISE OF AIR 
TEMPERATURE, WITH PROMINENT DIURNAL VARIATION; GRAD- 
UAL RISE OF SEA TEMPERATURE; SLIGHT DECREASE OF REL- 
ATIVE HUMIDITY; SLIGHT INCREASE OF VAPOR PRESSURE 
(ABSOLUTE HUMIDITY); POSITIVE CORRELATION BETWEEN 
SHORT-PERIOD VARIATIONS OF VAPOR PRESSURE AND RELA- 
TIVE HUMIDITY, AND NEGATIVE CORRELATION WITH LONG- 
PERIOD VARIATIONS; CURVE OF DIFFERENCES BETWEEN AIR 
TEMPERATURE AND SEA TEMPERATURE (tg-tc) FOLLOWS 
CURVE OF AIR TEMPERATURE, BUT DOES NOT FOLLOW VERY
