• 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.
