Adverse weather and climatic phenomena – a set of weather and climatic phenomena that create certain problems for human life.
Drought is a prolonged and sustained deficit of precipitation in areas with sufficient moisture. Drought is associated with an increase in air temperature and a decrease in its relative humidity during the warm season. Droughts are usually accompanied by dry winds. This is a hot, dry wind. It literally “sucks” the soil moisture. Droughts and dry winds result in the depletion of soil moisture reserves, which leads to a reduction or even death of the crop yield.
Light frosts represent a certain danger for agriculture when temperatures fall below 0ยบ in early fall and late spring. Frosts are most dangerous during flowering of fruit and berry crops such as apples, pears and currants.
Among the hazards to life and human activities are hurricanes – high velocity winds (over 30 m/s), of great destructive power. The occurrence of hurricanes is associated with cyclones, which have an extremely low atmospheric pressure in the central part. Hurricanes tear the roofs off houses, uproot trees, overturn telegraph poles, damage power lines, etc.

In some cases heavy fogs, i.e. droplets of water accumulating in the air, can be dangerous for people. As a result, air transparency is sharply reduced, visibility conditions deteriorate, which creates problems in the operation of any means of transport.

You can shelter from the cold and snow in a house, but your home must not only be lit, but also heated. This means that more fuel must be burned per person, i.e. more money must be spent. Because of the unfavorable climate we have to repair roofs and roads more often and clear snow drifts. Most of the arable land in our country is in the zone of risky agriculture: where there is enough heat, but not enough moisture, and vice versa. Periodic droughts also exacerbate the picture. In addition, extremely low temperatures are possible in most of the territory. One important consequence of the severity of climatic conditions is the persistence of permafrost on a large part of the territory.
