What impact will it have on agriculture?

Cold wave is a climatic activity in which cold air spreads southward from the Arctic and Siberia. As cold air, the arrival of cold wave is often accompanied by heavy rainfall, snowstorm climate and sudden drop in temperature. However, the cold tolerance of most crops is not high. When the temperature drops below zero, crops will be frostbitten in a large area and even die.

Cold wave refers to the gradual accumulation of cold air in high latitudes, such as the Arctic and Siberia, forming a large-scale cold air flow. When the scale is large enough, it will spew out and spread from the North Pole to the south. The cold wave has a great influence. Under normal circumstances, the cold wave will cause the local temperature to plummet 10-20 degrees Celsius, which is usually beyond the tolerance range of crops, leading to frostbite and even death of crops in a large area. Besides cooling, cold wave weather is often accompanied by rain, snow and frost. Where the cold wave strikes, there will be long-term rain and snow weather, especially the hail and frost weather will have a serious impact on crops.

The strong cooling caused by the cold wave will have a serious impact on the growth of crops.

The cold wave usually causes the local temperature to drop 10-20 degrees Celsius, which is unbearable for most crops. Various plants have different cold tolerance in different growth cycles. For some crops in the early growth stage, this large-scale cold wave is undoubtedly a serious blow. Therefore, the cold wave usually causes serious freezing damage to crops.

Rain, snow and frost accompanied by cold wave will also have an impact on crops.

As far as crops are concerned, most of them like light. Only when plants are irradiated by sunlight can they carry out photosynthesis better and accelerate the growth process. After the arrival of the cold wave, accompanied by rain, snow and frost, the local area will be in cloudy and cold weather for a long time, and long cloudy days will affect the photosynthesis of plants. In addition, frost will also lead to large-scale frostbite and even death of crops, resulting in serious production reduction.

There will be some guidance before the cold wave comes, so we should find it in time and prepare for it.

The cold wave is extremely harmful, but there are also signs. Relevant local departments should find out in time, take systematic preventive measures and take corresponding treatment measures for crops to minimize the losses caused by the cold wave.

How many days will the fog in Liaocheng last?

1 day.

Liaocheng Meteorological Observatory upgraded the foggy yellow warning signal to foggy red warning signal on February 9, 2022 16: 24. It is estimated that there will be extremely strong fog with visibility less than 50 meters in the counties and cities under the jurisdiction of our city from tonight to tomorrow morning. Please take preventive measures.

In foggy days, the horizontal visibility distance of all parties concerned drops below 1000m to prevent people's vision from blurring. Affected by cold air and strong winds, it is expected that the foggy weather will gradually dissipate tomorrow morning. Please arrange your life and production reasonably according to the weather changes.

Special weather phenomenon, please explain, thank you.

Because the atmospheric temperature is inherently high in summer.

The weather is fine before noon.

Water vapor evaporates rapidly with the rise of hot air.

Evaporating water vapor condenses at high altitude, forming cumulonimbus clouds (also known as convective clouds at this time, this time is often in the afternoon.

Cumulonimbus clouds accumulate and eventually form heavy rain or hail when the hot air below can't support them.

Often the higher the ground temperature, the greater the rain or hail!

This phenomenon is very common in tropical rainy season and temperate summer, so it is not very special.
