During the Spring Festival， no matter going home to visit relatives or traveling， "on the road" has become the normal state of many people. The Spring Festival of 2015 is in February， which is a season of short warmth followed by cold， during which the weather is very complicated and it is prone to appear more severe weather conditions， which will have an impact on our travel safety. During the Spring Festival when the weather is complex and changeable， how about the overall weather situation？ What disastrous weather should we prevent？
Cold wave and steep descent of temperature often occur
Temperature in February fluctuates severely. Cold wave and steep descent of temperature， which are almost the worst disastrous weather in February often occur， therefore， in February， it is prone to having a cold. Cold wave weather has a wide range of influences， and causes more serious and diverse disasters， such as cold damage， strong wind， freeze injury， icy road and snow retention caused by steep descent of temperature.
Counter
measures
Do not be hurry to change the thick winter clothes when the temperature fluctuates to prevent colds； take warm keeping and skid prevention measures to prevent falling down on slippery road； and call for help as soon as possible in the event of being trapped in the road by snowstorm.
Continuous rain and wet cold in the southern part of China brings discomfort
At the beginning of February， rainfall in the southern part of China gradually increase， but widespread heavy rainfall generally will not appear， mostly is continuous rain. However， prolonged rain causes humid air， coupled with lower temperature， the wet cold "magic attack" will make people in the southern part of China， where has no heating uncomfortable.
Counter
measures
Maintain the room well ventilated， and reduce indoor humidity with a moisture absorber or a dryer if necessary； put the clothes in the closet when they are completely dry in the air or dried manually； regulate your mood by yourself， properly take part in physical exercise to remove moisture in the body.
Cold wave and steep descent of temperature often occur
In North China， Northeast China， Inner Mongolia， Xinjiang and other places， it is possible to occur snow disaster in February. In the south， it is still necessary to prevent ice and freeze damage in February. Severe ice and freeze damage will cause large-scale power failure， water and gas supply cutting off in cities and towns； frozen roads and traffic disruption will lead to severe detention and congestion of vehicles and people in spring festival transportation. Counter
measures
Do not make long-distance running， play football and do other strenuous activities； wear a mask to shelter some pollutants when going out； the old， children， pregnant women， and patients suffering from heart attack had better not go out in haze weather； eat more fruits and foods which can clear the lungs.
Fog and haze are still easy to occur
Although the weather becomes warmer in February， the temperature is still relatively low， therefore， water vapor in the air is easy to become saturated and form fog， and the atmosphere will stabilize in the time gap that the cold air comes， besides， heating season in north China is not over， which makes that haze is easy to occur. When there is fog and haze， poor air quality will do harm to respiratory system and cardiovascular system.
