When does the lowest temperature appear in a day?

The lowest temperature in a day appears before and after sunrise, and the related explanation is as follows:

1, at night, the ground will lose heat, which will gradually reduce the temperature. After sunrise, the sun began to shine on the earth and the temperature began to rise gradually. Therefore, the lowest temperature in a day usually appears around sunrise in the morning. This is not absolute. In some cases, for example, in sunny weather, more heat may be lost at night, resulting in a faster temperature drop.

2. Under the weather conditions with thick clouds and weak wind, the temperature change may be gentle, and the lowest temperature may appear later. The lowest temperature in a day will also be affected by the season and geographical location. In winter, the lowest temperature usually appears earlier because of the long night time.

3. In tropical areas, due to the hot climate all the year round, the minimum temperature may not be as obvious as that in temperate areas. The lowest temperature in a day usually appears around sunrise in the morning, but it is also affected by many factors. To know the specific minimum temperature time, we need to refer to the weather forecast and local climate characteristics.

The influence of weather on life

The influence of weather on daily life is obvious. In hot summer, people need to replenish water frequently to avoid heatstroke and dehydration. In the cold winter, people need to wear thick clothes to keep warm and avoid colds and other respiratory diseases. In addition, the weather also affects the way people travel. In rainy or snowy days, people may need to choose different means of transportation to avoid road congestion.

The influence of weather on physical and mental health can't be ignored. Studies have shown that sunlight can promote the synthesis of vitamin D and contribute to bone health. At the same time, sunlight can also promote the brain to secrete neurotransmitters such as serotonin, which is helpful to relieve mental diseases such as depression. However, excessive exposure to the sun can also lead to sunburn and other problems.

3. Weather also has an important influence on agriculture, energy and tourism. Agriculture needs to adapt to different climatic conditions and weather changes, and choose suitable planting varieties and planting time. Energy consumption will also be affected by the weather. For example, heating in cold winter requires more energy.
