What is the approximate temperature in April?

Spring in April really begins. As the saying goes, "It's ten days after Tomb-Sweeping Day", which means that there are still ten days in Tomb-Sweeping Day, and the temperature will be repeated, so we should pay attention to keep warm.

Generally, in Tomb-Sweeping Day, there will be a wave of late spring cold. After the late spring cold, the weather will start to pick up. Late spring cold refers to the weather phenomenon that the temperature rises rapidly in early spring (generally refers to the end of February and the beginning of March), but the temperature in late spring cold (generally refers to April) is lower than normal. Long-term rainy weather or frequent cold air intrusion, or under the control of continuous cold and high pressure, strong radiation cooling in sunny nights is easy to cause late spring cold. The climate is changeable in early spring. If the cold air is strong, the temperature can drop to below 10℃, even in rainy and snowy weather. At this time, it is often sunny during the day, which makes people feel that "warm wind makes tourists drunk", but it is chilly in the morning and evening, which makes people feel "chilly in spring". This unpredictable "fickle" weather is what is commonly called "cold spring".

20 18 What's the temperature like in April? At the beginning of April, it has reached the fifth solar term of the year, with beautiful spring and pleasant climate. During my stay in Tomb-Sweeping Day, the weather temperature was generally around 15-20 degrees.

However, it rained lightly around Tomb-Sweeping Day (April 5th) this year. At this time, the atmospheric circulation in East Asia has changed from winter to spring. The ridge of westerly belt moves frequently, and the low-level high and low pressure appear alternately. The temperature in the Jianghuai area changes greatly, and unstable precipitation such as thunderstorms gradually increases.

April weather and temperature in 20 18 The temperature in northern China rises rapidly, with little precipitation and dry and windy weather, which is the time of dusty weather in a year. The average temperature in April in many northern areas has reached 10℃ ~ 15℃.

Although spring has not yet come in parts of northeast and northwest China, according to the surface climate data of China 197 1 ~ 2000, the average extreme maximum temperature in Hohhot in March has reached 19.4℃, Xining 23. 1℃ and Qiqihar 23.0℃. Mid-April is the Qingming Festival, and the mountain

Rainfall in the middle and lower reaches of the Yangtze River increased significantly. Except for the eastern coast, the average rainfall in April in most areas of the south of the Yangtze River is above 100 mm. If the cold air is strong, there will be low-temperature rainy weather with the daily average temperature below 10℃ for more than three consecutive days, and insufficient sunshine will seriously affect the growth of warm crops such as early rice and cotton.

South China is located in the south, close to the ocean, and when it is affected by the front formed by the intersection of cold and warm air, heavy precipitation begins to appear, which is called the pre-flood season in South China. Among them, the average rainfall in northern Guangdong and northern Fujian in April exceeded 200 mm, and the rainfall intensity ranked first in the country. Whenever the thermal convection in the rain belt develops vigorously, there will be strong convective weather such as thunderstorms and heavy rain, which is worthy of vigilance.

During the Qingming period, the average daily temperature in most parts of China has risen to above 12℃ except the northeast and northwest regions. From north to south to the inside and outside of the Great Wall, there is a busy scene of spring ploughing everywhere. "In the Qingming Festival, the wheat grows for three days", the wheat in the south of Huanghuai is about to start heading, the rape has blossomed, and the wheat in the northeast and northwest regions has also entered the jointing stage. In the later stage, we should pay close attention to fertilizer and water management and pest control.
