METEOROLOGY – PRECIPITATION CALCULATOR
Graupel Formation Temp
A precise tool.
What is the Graupel Formation Temp & How does it work?
Graupel, also known as soft hail, is a type of precipitation that forms when supercooled water droplets in clouds come into contact with snowflakes. As the water droplets freeze onto the snowflakes, they form small, puffy ice particles.
The formation of graupel is influenced by several factors, including temperature and humidity. Graupel typically forms in temperatures between -10°C and 0°C (14°F to 32°F). This range allows the supercooled water droplets to freeze onto the snowflakes without sublimating into vapor.
T_{graupel} = -frac{1}{2} times (T_{max} + T_{min})

Frequently Asked Questions
What is graupel?
Graupel, or soft hail, forms when supercooled water droplets freeze onto snowflakes in cold temperatures between -10°C and 0°C.
How does graupel form?
Graupel forms when supercooled water droplets in clouds come into contact with snowflakes, freezing onto them to create small, puffy ice particles.
What temperature range is ideal for graupel formation?
Graupel typically forms in temperatures between -10°C and 0°C (14°F to 32°F).
Can graupel form at warmer temperatures?
While rare, graupel can form at slightly warmer temperatures if the humidity is high enough.
How does humidity affect graupel formation?
High humidity levels can facilitate graupel formation by providing more supercooled water droplets in the atmosphere.
Is graupel dangerous?
Graupel is generally not dangerous but can cause slippery roads and disrupt travel if it accumulates in large quantities.
What is the difference between graupel and hail?
Graupel is softer and puffy, formed by freezing water droplets onto snowflakes, while hail is harder and denser, formed by repeated cycles of melting and refreezing within thunderstorms.
