进入深秋季节以后,来自西伯利亚的冷空气不断南下,使昼夜温差逐渐加大,大气湿度也明显下降,秋风萧瑟,天气一天比一天冷。这段时间气温下降较快,一次较强的冷空气往往会带来7摄氏度左右的剧烈降温。随着气温持续降低,气候偏于干燥,这样的时节,身体衰弱的老年人无疑容易患各种疾病,其中气象过敏症就是最常见的疾病。
After entering the autumn season, the cold air from Siberia continued to move southward, causing the temperature difference between day and night to gradually increase. The atmospheric humidity also dropped significantly. The autumn wind blew and the weather became colder day by day. During this time the temperature dropped rapidly, a strong cold air will often bring severe cooling about 7 degrees Celsius. As the temperature continues to decrease, the climate tends to be dry. In such a season, debilitated seniors are undoubtedly susceptible to various diseases, of which meteorological allergies are the most common diseases.
