About Precipitation

• In warm areas, the precipitation is mostly rain.

• In colder areas, the precipitation is snow or ice rain.

• The five most common type of Precipitation is rain, snow, hail, freezing rain, and sleet.

Rain

• Rain is the most common type of precipitation.

• The size of a rain drop is about 0.5mm in diameter.

• Rain could be smaller drops called mist and drizzle.

Sleet

• Sleet is precipitation that falls through a layer of 32°F or 0°C, the freezing point of water.

• As the water falls it turns in to ice.

• The ice is 5mm or less in diameter.

Freezing rain

• Freezing rain is when precipitation falls though a layer of cold air near the ground and it does not freeze.

• The rain freezes when it hits a something cold.

• It may break tree branches and/or even take down a power line.

Hail

• Hail is round pellets of ice larger then 5mm in diameter.

• Hail is formed in cumulonimbus clouds during t thunderstorm.

• starts as sleet it turn in to a hailstone every layer of 32°F or 0°C air it goes through.

• Soon it will fall to the ground.

• It can damage crops, buildings, and vehicles.

Snow

• Snow is water vapor that turns in to crystals called snow.

• Snowflakes are all different shapes, sizes, and the all have six sides or six branches

• Snow flakes clump together and to have six sides.

The way to measure rainfall

• The way to measure rainfall is a rain gauge.

• A rain gauge is an open ended can or tube that collects rainfall.

• The rain is measured by putting a rule n to the water.

Cloud seeding

• Cloud seeding is tiny ice crystals of dry ice and iodide.

• It’s spread by an airplane or a jet.

• Water vapor condenses on to the silver iodide.

• The dry ice freezes the water faster so it will fall to the ground faster.

Key term #1

• Precipitation: Falling products of condensation in the atmosphere; rain, snow, hail, and etc.

Key term #2

• Rain gauge: an opened ended can or a tube that collects rainfall.

Key term #3

• Drought: Long dry periods with little or no rain.
