What is the difference between freezing and frosting?

Weather of Arabia - We often get confused with some weather terms that may differ in meaning, but they are somewhat close, which leads to a misunderstanding.

We also get confused with the words frost and freezing , which may seem at first glance to be synonymous with the same content, and actually there is a big and clear difference between them, but non-specialists may not realize it.

What is the difference between freezing and frosting?

In short, frost occurs when the air temperature is equal to the dew point, but freezing occurs when the air temperature is different from the dew point.

To understand this, you must first know what is the meaning of frost and what is the meaning of freezing? How does each of them happen? And what is the relationship of their occurrence with dew?

What is frost?

Frost results when the air temperature drops to zero degrees Celsius or less, as water changes from the liquid state to the solid state, or water vapor changes directly from the gaseous state to the solid state.

It should be noted that when frost occurs in an agricultural area, this affects the fluids in the tissues of plants and may lead to their destruction. Know how to protect plants from the dangers of frost

Among the types of frost ; Radiation frost.

What is radiation frost ?

It occurs when the air temperature drops to the dew point, so that the air becomes saturated with water vapor, where the temperature is equal to the dew point, then the water vapor condenses and turns into water droplets on the surfaces and dew forms.

If the temperature drops to zero degrees Celsius or less, the water droplets freeze and form frost.

So frost may form when the air and dew temperatures are equal . in contrast to freezing.

What is freezing?

Freezing occurs if the air mass is very cold and dry, that is , there is a big difference between the temperature and the dew point , and this means that no matter how low the temperature is, even if it reaches zero or less without reaching the dew point, here dew does not form, and therefore frost does not form, but it does happen Freezing if water is available on the surfaces.
