2 4 What does sleet mean?

Sleet: Semi-melted snow (wet snow), or rain and snow falling at the same time. It mostly occurs when the temperature near the surface is slightly above 0 degrees Celsius.

A weather phenomenon in which raindrops and snow fall at the same time.

Snow is a crystalline body of water. The clouds in the sky meet the cold air, the temperature drops, and the water vapor forms ice crystals under the combined action of low temperatures and tiny dust. The volume is constantly increasing. The density exceeds the air and it falls, that is, it snows.

Clear skies generally don't snow. However, due to the different cloud layers, one layer is snow and the other layer is rain, so sleet can be formed.

To put it bluntly, the weather is not very cold, and the snow in the air is 2-4 because the temperature is 2-4, so part of the snow melts into sleet.

The temperature was moderate from 2 to 4 degrees Celsius, and the weather conditions were sleet.

Rain and snow fall at the same time as sleet.

It is a special precipitation phenomenon formed by the mixing of rain and partially melted snow and falling at the same time.

The special condensation of sleet requires temperature, which occurs mainly when the temperature of the part of the atmosphere closest to the ground is slightly above the freezing point of water (0 or 32).

In order to melt snow falling from high clouds into rain, the thickness of the warm air layer varies from 230 m to 460 m.

Other terms related to sleet.

Wintry Shower: An informal meteorological term first used in the United Kingdom to refer to a mixture of rain, graupel and snow. Although there is no official standard for this term, in the UK it is not used when snow is noticeable on the ground, but generally when the ground temperature is above 0 and the atmosphere is below 0, where the ground temperature prevents snow accumulation and produces other substances on the ground.

"Wintry Mix": Used mostly in the United States, it is used to refer to a mixture of freezing rain, ice particles, and snow. Unlike the previous term, this term applies when both the ground and atmosphere temperatures are below zero.

In addition, the term also applies to the accumulation of ice or snow on the ground that may occur.

Sleet is a special precipitation phenomenon formed by rain mixed with partially melted snow and falling at the same time.

The phenomenon of sleet is temperature-demanding, and it occurs mainly when the temperature in the closest part of the atmosphere to the ground is slightly above the freezing point of water. When the atmosphere of the melt layer is between 230m and 460m thick, rain and partially melted snow will naturally mix together and sleet will form when it falls to the ground.

Sleet hazards

In the early morning after the glass freezes and the warm wind blows the sleet, it is common to see the front windshield icing, which seriously affects the vision and poses a safety hazard if it is not treated. If not handled properly, not only will it have little effect, but it may also cause damage to the vehicle. Sleet is less hard and more transparent than hail and freezing rain, but there are some traces of ice crystals.

During the rain (snow) period, the temperature is low and the humidity is high, and the disease monitoring should be strengthened in the management, special attention should be paid to the occurrence and spread of vegetable blight and gray mold, and the disease prevention agent spraying protection should be used in advance.
