Instruction
1. There are many signs thanks to which it is possible to define weather for tomorrow: this existence and nature of clouds, temperature drops during the day and discrepancy with the correct daily course, change of atmospheric pressure, and even behavior of animals and birds. Set of all signs give complete idea of tomorrow, about volume what weather should be expected tomorrow.
2. Signs of approach grozyv morning hours of day sharp formation of cumulus clouds is observed and during the day accumulation of masses with simultaneous warming continues. Pressure at this moment unstably or gradually falls. In this case prepare for a thunderstorm after a lunch. The clouds floating on the sky in the form of long and narrow pyramids foretell a short thunderstorm. The movement on the sky of clouds in the form of enormous blocks, with a dark lower layer – signals of a long thunderstorm. By the evening, air became warm and stuffy, the sky clouded continuous clouds, wait for a night thunderstorm.
3. Signs of improvement of weather Indicators of a barometer grow up. During a summer season when changing weather the air temperature goes down. In the evening day on the western part of the sky cloudless gleams appear. If the sky sharply clears up and wind abates, then improvement of weather will last not for long.
4. Signs to a steady pogodyuzha many days keep high atmospheric pressure or sharp increase after bad weather is observed. A cloudless clear sky, only in the morning in the spring, in the summer or it is possible to see cumulus or plumose clouds in the fall, but by the evening you will not notice in the sky a uniform cloudlet. Temperature usually keeps on the correct daily course according to season: in the summer – in the afternoon warmly, and at night temperature falls and becomes cool; in the winter – at night at the clear sky the frost is felt, and in the afternoon the frost considerably weakens. If easy whiff of a breeze is observed in the afternoon, then at night wind gradually abates and absolutely stops. Near the wood the movement of wind is felt from the wood in the afternoon. By the evening and at night day wind changes the direction woodward. Sometimes in the evenings in low places there is fog and keeps all night long, but with the first beams of the sun the fog dissipates. A morning and evening dawn of beautiful golden color with pinkish gleams.
5. Signs of change of a clear weather on nenastyeponizheny pressure in the atmosphere – warns us about deterioration in weather. Temperature increase during a winter season and a sharp cold snap is characteristic of temperature condition in the summer, at the same time the difference between day and night temperature values decreases. Sometimes in the evening, in comparison with day indicators, air temperature increases. Indications of speed of wind at different times day constantly changes. Wind can weaken and gradually calm down. Strengthening of wind with simultaneous pressure drop foretells about cyclone approach. Without changing the direction, wind sharply calms down - it is sign of fast change of the direction of wind. In the sky from West side clouds begin to be formed. The big congestion of plumose is high – layered and layered cumulonimbus clouds warns about change of weather conditions. The movement of clouds with high speed is observed – it foretells passing of a warm cyclone with a long drizzle. Fast approach of a cyclone characterizes a congestion of plumose clouds in the form of a fan and moving from West side. By the end of clear and warm day, in the late afternoon in the sky big colonies of clouds which gradually are condensed and increase in volume began to appear. It is sign of approach of rainy weather. The lack of dew on a grass and low creeping fog warns too that we are expected by sharp deterioration in weather. The evening sun goes to clouds, and dawns are painted in bright red color. Anyway the nature has no bad weather.
