"Trains also have wading experience!"
"You know"
Precipitation is not necessarily rain
But rain snow and hail
And still fall from the atmosphere
There are two basic conditions
There must be enough water vapor and condensation nuclei in the air
And the temperature drops to the point where it can condense
The condensation nucleus here refers to a suspended particle
Through the condensation of water vapor in the atmosphere
"Now the train can still run the railway"
Precipitation is rain and snow falling in the atmosphere
And the fall of hail because precipitation is a general term
Fog haze frost and dew do not belong to this category
After all there is a prescribed process
Rainfall and precipitation are not synonymous
But rainfall is a kind of precipitation
Its beginning is the evaporation of water surface
Plus the process of cooling and condensation
Precipitation is divided into three types
Based on the reasons and forms of air rising
When moist air rises and becomes cold
The precipitation it forms is called convective rain
If the air moves through the mountain climbing
Followed by the process of temperature drop
And then to the windward slope through condensation
This is called orographic precipitation
"Now the train can still run the railway"
Precipitation is rain and snow falling in the atmosphere
And the fall of hail because precipitation is a general term
Fog haze frost and dew do not belong to this category
After all there is a prescribed process
Rainfall and precipitation are not synonymous
But rainfall is a kind of precipitation
Its beginning is the evaporation of water surface
Plus the process of cooling and condensation
The precipitation produced after cold air meets warm air and warm air rises is called frontal rain
A period of precipitation is defined as the depth of rainwater accumulation without evaporation infiltration and loss
In millimeters
Daily precipitation and so on can be deduced from this
The distribution of precipitation in the world is uneven
Similar to the distribution of temperature
Just add land and sea factors and terrain factors
Cherrapunji is the place with the richest precipitation in the world
Precipitation is rain and snow falling in the atmosphere
And the fall of hail because precipitation is a general term
Fog haze frost and dew do not belong to this category
After all there is a prescribed process
Rainfall and precipitation are not synonymous
But rainfall is a kind of precipitation
Its beginning is the evaporation of water surface
Plus the process of cooling and condensation
"This is also why there is no train in Cherrapunji right"
"After all there is a dead zone for trains!"
