Thermospere
Rain turns to sleet or snow when the temperature drops to or below 0 degrees Celsius (32 degrees Fahrenheit). The raindrops freeze into ice pellets (sleet) or snowflakes when the temperature in the atmosphere reaches this threshold.
In the troposphere, the temperature drops. In the stratosphere (layer above the troposphere) it increases with elevation. In the mesosphere, temperature drops again with elevation. In the theromosphere, it goes up again (to nearly stellar surface temperatures).
Ice crystals would form when the temperature of the air drops to 0 degrees Celsius or below. Since the dew point temperature is -6 degrees Celsius, the air would need to cool further to reach the freezing point of water and allow ice crystals to form.
On average, the temperature drops by 2 degrees Celsius for every 1,000 feet of altitude gained. So, 26,000 feet x 2 degrees Celsius = a 52 degree difference from the ground, in Celsius. To convert to Fahrenheit, remember the temperature drops by 3.6 degrees Fahrenheit, on average, for every 1,000 feet of altitude gained. So if your having a 100 degree heatwave on the ground, don't lick any poles up top. . . The temperature will be a balmy 6.4 degrees Fahrenheit.
If the air temperature drops to 25 degrees Celsius and the relative humidity remains at 60 percent, the dew point will not be reached. The dew point is the temperature at which air becomes saturated and condensation forms. In this case, the temperature would have to be lowered further for the dew point to be reached.
The temperature dropped by 11 degrees Celsius.
Rain turns to sleet or snow when the temperature drops to or below 0 degrees Celsius (32 degrees Fahrenheit). The raindrops freeze into ice pellets (sleet) or snowflakes when the temperature in the atmosphere reaches this threshold.
The temperature rarely drops below 18 degrees Celsius.
Pipes can freeze when the temperature drops below 32 degrees Fahrenheit (0 degrees Celsius).
The average surface temperature on Mars is 20 degrees Celsius at noon at the equator. At the poles, the temperature drops down to -153 degrees Celsius.
Pipes can freeze when the temperature drops below 32 degrees Fahrenheit (0 degrees Celsius).
House pipes can freeze when the temperature drops below 32 degrees Fahrenheit (0 degrees Celsius).
Pipes in a house can freeze when the temperature drops below 32 degrees Fahrenheit (0 degrees Celsius).
Water pipes can freeze when the temperature drops below 32 degrees Fahrenheit (0 degrees Celsius).
Underground pipes can freeze when the temperature drops below 32 degrees Fahrenheit (0 degrees Celsius).
Frost forms when the temperature drops below freezing, typically around 32 degrees Fahrenheit (0 degrees Celsius).
Frost starts to form when the temperature drops below freezing, which is 32 degrees Fahrenheit or 0 degrees Celsius.
