What will happen to the temperature in the same place at different times of the day?

The change of temperature is caused by the angle of sunlight shining on the ground and the length of day and night. The temperature at different times on the same day is related to the solar altitude angle. The greater the altitude angle, the higher the temperature. The smaller the altitude angle, the lower the temperature.

Before sunrise, the temperature is the lowest in a day. After sunrise, the temperature rises gradually, reaching the highest value in a day around 2 pm, and then the temperature drops until the lowest temperature before sunrise the next day.

natural cause

The temperature in a certain place changes periodically not only because of the change of solar radiation, but also because of the movement of the atmosphere rather than periodically. The change of actual temperature is the result of the interaction between these two aspects.

If the former plays a big role, the temperature changes periodically; On the contrary, it shows an aperiodic change. However, from the general trend and most cases, the periodicity of daily and annual temperature changes is still the main one.

Various components in the heat balance, such as radiation difference, latent heat and sensible heat exchange, are affected by different control factors. Astronomical factors such as latitude and season have obvious zonal and periodic characteristics.

However, the nature, topography and weather conditions of the underlying surface, such as cloud cover and atmospheric humidity, all have non-zonal characteristics. At the same time, the influence of these factors is different in different places, so the temperature distribution caused by the change of heat budget is also uneven.
