What is precipitation and its forms?
Precipitation
Precipitation or precipitation is a popular term of meteorology when water falls on the surface in the form of liquid or solid, it is called precipitation.
The process of continuous condensation in free air helps to enlarge the size of the condensed particles and they do not stop floating in the air because the resistance of the air fails to stop them against the force of gravity then they fall to the surface of the earth . Therefore, the release of moisture after the condensation of water vapor is called precipitation. It can be in liquid, gas or solid state.
Precipitation forms
solid - snow, hail
liquid -rain, splash
Gas - dew, fog, mist
Spray: When very small droplets of equal size 0.5 mm in diameter. is less than. If it falls on the ground, it is called a spray.
Rain- When precipitation occurs in the form of water, it is called rain, so when small drops of water fall on the surface in the form of big drops, then it is called rain. Hence rain is a form or type of precipitation.
Snowfall: When the temperature is below 0°C, the atmospheric humidity turns into snowflakes. These tiny snowflakes make up snowflakes. Which become big and heavy and start falling on the ground. Then the precipitation occurs in the form of snowflakes which are called snowfall.
Hail : Sometimes raindrops after being released from the cloud turn into small spherical solid pieces of ice and reach the surface of the earth which is called hailstone.They are formed by rainwater that passes through cold layers. These hailstones consist of several concentric layers of snow, one on top of the other.
Freezing rain - Freezing rain is the drop of frozen rain or frozen drops of water from melted snow. Freezing rain occurs when a layer of air with the freezing point temperature falls on a half-frozen layer near the surface.
Dew Point - The temperature at which water vapor condenses into water is called dew point. The dew point depends on many factors, including pressure, relative humidity, etc.
Frost - Generally the long nights of winter are colder and sometimes the temperature drops to or below freezing point.
In such a situation, the water vapor directly gets converted into microscopic snowflakes without changing into liquid form, it is called frost.
Mist is also like fog, the only difference is that it becomes more dense. Where fog is visible to us in winter, mist arises due to increased moisture content in the air during rainy days.
Blight - The steam found in the air, which falls apart from the air in the form of solid and fine particles of water and appears to be deposited on the substances.
Fog - The amount of water vapor in the air becomes constant when the relative humidity is 100 percent.
This leads to the addition of excess water vapor or a drop in temperature that triggers condensation.
Small water droplets condensed from water vapor spread in the form of fog in the atmosphere.
Condensation - The phenomenon of gas becoming liquid is called condensation. It is the opposite of evaporation. It is often used only in the context of the water cycle. Rain is also a type of condensation.
