What is the weather like in Xiamen? Is it hot?
Climatic characteristics of Xiamen:
The high temperature period is long, the temperature changes little, and autumn and winter are even spring.
Hot and humid in the same season, water and heat are well coordinated and the climate is humid.
The seasonal alternation of monsoon circulation is obvious
The weather in January is generally cold and dry, which is the lower month of the year after February. Over the years, the daily minimum temperature is lower than 2/3 of 10'C in the second half of this month. 1 month is the lowest month in the whole year, with more sunshine, less clouds, higher wind speed and stable weather.
The weather in February is similar to 1 month, but the annual average temperature is the lowest, and the extreme minimum temperature also appears in February, with the average temperature of about 12 degrees and the extreme minimum temperature of about 2 degrees. In February, the northeast monsoon changed obviously, the general wind speed decreased, and the wind direction changed from northeast to east-northeast. At the same time, it is also the month when the invasion of polar continental air mass is weakened. Due to the increase of atmospheric disturbance, February is the month when rainfall begins in a year. Although the rainfall is not much, it indicates the end of the dry season.
In March, the temperature rises and the relative humidity increases. March is the most active time in the center of the year, the cloud cover is the largest month of the year, and the average sunshine is second only to the lowest February. Fog is the most common month of the year.
In April, the northeast monsoon receded and gradually disappeared, the southeast monsoon began to appear and gradually developed, and the atmospheric circulation almost stopped, causing some important consequences:
First, the ground temperature rose sharply, with the largest increase in one year, with an average increase of 4.3 degrees;
Second, the local wind strengthens and dominates the circulation, and the strong sea breeze blows almost continuously. Local convection is quite active.
April is also the month with more hail over the years.
In May, the southeast monsoon developed further. May is the rainy season, and the average start date is early, around May 5. The rainy season lasts until June, and the end date is late June, about June 25th. The average relative humidity reaches 84%, second only to June in a year. May is the beginning of real summer, and the temperature and rainfall continue to increase, which is the month with the biggest change in rainfall in a year. This is the earliest month of typhoon.
June is the month with the most rainfall and the most rainstorm in a year, with the daily rainfall exceeding 50.50 mm, mainly during the Meiyu period. The number of rainstorm days accounts for about 40% of the annual rainstorm days. This month's average relative humidity is the highest in the whole year, reaching 86%, but the wind speed is the lowest, with an average wind speed of 2.9m/s, which is also the month with the fewest windy days of magnitude 8 or above, with an average of 1.2 days. Due to the rainy weather, the daily average temperature change range is also the smallest in the whole year, only 5.8 degrees.
July has the highest total solar radiation and the highest average temperature in a year. Mainly controlled by subtropical high, the weather is sunny and hot, and it is prone to drought. But sometimes the subtropical high weakens or moves eastward, and the moist ocean air can invade. Thunderstorms or showers often occur due to strong thermal convection or convergence of high-altitude airflow in the afternoon. The frequency of typhoons has increased this month. At the same time, the average water vapor pressure is the largest month of the year.
August is similar to July, with the highest temperature, with an average temperature of about 28 degrees and an extreme maximum temperature of about 38 degrees. At the same time, August is the month with the largest number of typhoons and the month with the largest number of typhoons in history.
In September, the weather turned into the northeast monsoon again. The southeast monsoon retreated and the northeast monsoon developed. The temperature dropped slightly and the precipitation decreased obviously.
Winter winds prevail in 10, and the temperature drops greatly. Rainfall and 1 1 month are the least months. Therefore, the sunny days are greatly increased, the cloud cover is reduced to the lowest value in the whole year, and the air is usually dry. But the annual average wind speed is the highest, which is 4.2m/s.
1 1 month, like1month, the winter wind is completely prevalent and the temperature drops further. The temperature at the end of the month is 4 degrees lower than that at the beginning of the month. Since 1 1 month, the temperature has dropped below 20 degrees. The precipitation and daily precipitation in 1 1 month are the lowest in the whole year, only 25.5 mm and 0.7 mm, but the average wind speed is very high, which is only 4 m/s after1month.
1February, the temperature continued to drop, but the lowest temperature was still 14 degrees. Due to less precipitation, the number of days without precipitation is second only to 1 1 month, reaching 26 days, and other aspects are similar to 1 1 month.
