Fig. 36.—Barometer Complete.
To remember these forecasts easily they may be briefly stated thus:
- (1) A high barometer shows fair weather.
- (2) A low barometer shows bad weather.
- (3) A sudden fall of the barometer shows a coming storm.
- (4) A constant high barometer shows continued fair weather.
To Forecast the Weather by Signs.—It will seldom happen that a boy who goes camping, or one who otherwise wants to know what the weather is likely to be on the morrow, will have a barometer to consult, so the next best thing is to know how to read the weather signs:
(1) “Red at night is the sailor’s delight” is an old forecast, and means that the morrow will be a fine day.
(2) “Red in the morning is the sailor’s warning,” which means that rain is coming.
(3) A golden sunset is a sign that a high wind is coming.
(4) A yellow sunset is a sign that rain is coming.
(5) When the Sun sets clear it is a sign of a fine day on the morrow.
