Encyclopedia article (1928–1936)
Bryson's Symptom (Bryson), in Basedow's disease, consists of noticeably shallow inhalation with abnormally reduced inspiratory chest expansion. 2, Breezes (from French brise--breeze), are coastal winds in tropical and partly in temperate countries, blowing from the sea by day and from the land by night. Breezes are almost always sharply pronounced in clear warm weather. When breezes change, a short period of calm is observed. The sea breeze brings air of lower temperature and higher humidity. The land breeze is characterized by greater fluctuations in temperature and humidity depending on local conditions. Breezes are also observed on lake shores. The cause of breezes: during the day, air heated over the land rises, and in its place flows a stream of air from the sea under the influence of increased pressure there. At night, conversely, air rises over the less cooled, and therefore warmer, sea, and the breeze blows from the shore. The speed of breezes is 1-5 meters per second. Inland, breezes penetrate 25-40 km and reach heights ('power' of the breeze) of up to 400-500 meters. Climatic and resort importance of breezes: equalization of the coastal climate (temperature and humidity), refreshing and calming effect on patients, ventilation of the air on coasts and in coastal valleys, and general hygienic importance. In resort areas of the USSR, breezes are especially developed on the Black Sea coast of the Caucasus and on the southern coast of Crimea.
