Sudden change of weather is capable to deliver a great deal of trouble, and in certain cases even to pose a threat for life. Knowledge of some signs foretelling a weather changing will allow to assess a situation correctly.
Instruction
1. The weather changing practically is always preceded by change of atmospheric pressure and humidity. Get a barometer in shop, make the simplest measuring instrument of humidity independently of a 10-15-centimeter piece of a trunk of a young fir-tree with a branch 30-40 cm long. Clean a stipitate and a branch from bark and fix not movably on a wall, having left a branch free – it will serve as a peculiar arrow.
2. At change of the humidity preceding rainy weather, "arrow" will deviate down. Before a clear sunny weather – up. Having studied instrument readings, make on a wall the corresponding tags – "Clearly", Peremenno, "Cloudy". Thanks to them you will be able to predict changes of weather rather precisely.
3. Study the main signs of a weather changing. So, change of a clear weather with cloudy is preceded by pressure decline. And the stronger the barometer "falls", the bad weather will be worse. About approach of rainy weather the swallows who are low flying above the ground, and bathing in dust sparrows signal.
4. Also will point to a bad weather: the smoke creeping on the ground, ants hide in ant hills, buds of flowers are closed, flowers of water-lilies leave under water, frogs loudly croak, the sunset is painted in red tone. If hens walk during a rain - bad weather will drag on. The rain is foretold by the appeared cumulus clouds. Plumose clouds signal about windy weather. If clouds quickly grow up and form several tiers - there will be a heavy rain.
5. The termination of a bad weather is preceded by the signs too. Pressure begins to grow, it is one of the most right signals. If day was rainy, but in the evening in the West appeared plainly a clear sky and the sun sets not in clouds, the next day will be clear. Approach of a clear weather is preceded by emergence of gleams in overcast. Wind becomes gusty that speaks about the end of passing of the storm front.
