The table shows that it is only during the months May to Au- 
gust that the winds from the sea come to exercise a greater influence 
on the meteorological elements at Danmarks Havn. The element 
which in this case is interesting beyond all others is the temperature. 
If we go over the tables of the three daily regular observations, in 
“Meteorologische Terminbeobachtungen am Danmarks Havn”, Medd. 
om Grenl. XLII, we are able to deduce the following: 
April: No noticeable difference between the temperature of the sea 
wind and the land wind. 
May: The sea wind nearly one degree colder than the land wind. 
June: The sea wind nearly one degree colder than the land wind. 
July: The sea wind nearly three degrees colder than the land wind. 
August: The sea wind nearly two degrees colder than the land wind. 
September: No noticeable difference between the temperature of the 
sea wind and the land wind. 
Characteristic of the sea wind is, besides a high percentage of 
moisture, a small wind velocity and a large decrease in the velocity 
of the wind according to the height. The consequence of this is 
that the sea wind generally only reaches a very small altitude, after 
which, through a zone of calm or with a bound, it becomes a land 
wind or south-westerly wind, which in these cases has common charac- 
teristics with the land wind. The kite-ascensions, very few in number,
