how does the atmosphere affect the biosphere
Over a long period of time, the atmosphere developed a ...
Light fluffy snow may only weigh about seven pounds per cubic foot. More average snow may weigh 15 pounds per cubic foot and drifted compacted snow may weigh 20 pounds or more…” Let’s figure this out… There are 7.48 gallons per cubic foot of water – that’s about 62.4 pounds.
If we ignore other factors, then one inch of snow is approximately equal to 10 -12 inches of snow.
More densely packed and wet snow is in the ratio of 8 inches of snow to 1 inch of equivalent rainfall, and more powdery snow is about 14 to 1 ratio. Obviously this is an approximation but a good one.
Define the dimensions of the volume of the snow sample as some base area times the depth of the snow. Now, keep the base area the same but melt the snow. Example: A 10 cm depth of snow with density 300 kg m-3 has a snow water equivalent SWE(mm) = 10 cm (300 kg m-3)/100 = 30 mm.
How many inches of snow equals one inch of rain? On average, thirteen inches of snow equals one inch of rain in the US, although this ratio can vary from two inches for sleet to nearly fifty inches for very dry, powdery snow under certain conditions.
Rainfall amount is described as the depth of water reaching the ground, typically in inches or millimeters (25 mm equals one inch). An inch of rain is exactly that, water that is one inch deep. One inch of rainfall equals 4.7 gallons of water per square yard or 22,650 gallons of water per acre!
Three days of temperatures at 50 degrees can melt 2 to 4 inches of snow. If temps fall below freezing at night, the process will be slower. The amount of moisture in the air can accelerate the melting process, while wind will carry away the moisture and preserve the snow pack.
1/10 (0.10) of an inch of rain – A light rain for 30-45 minutes, moderate rain for 10 minutes or heavy rain for 5 minutes. Small puddles would form but usually disappear after a short while.
As a rule of thumb, snow weighs approximately 20 pounds per cubic foot, or 1.25 pounds per inch of depth. Depending on moisture content, snow can weigh from 1 pound per cubic foot to over 21 pounds per cubic foot. NOTE: Any ice build-up on the roof would need to be added to this formula.
If it snows 12” of light and fluffy snow, it will weigh about 5.2 pounds. Unsurprisingly, wet snow is the heavy stuff. If it snows 5” of wet snow, it will weigh about 12.5 pounds.
The specific weight of water is 62.43 pounds (avoirdupois) per cubic foot.
A tenth of an inch of freezing rain becomes a nuisance. It’s not enough for power outages, but it can cause sidewalks and overpasses/bridges to turn slick. A half an inch of ice damages trees. Widespread power outages become more likely.
Snow Water Equivalent, or SWE, is a commonly used measurement used by hydrologists and water managers to gage the amount of liquid water contained within the snowpack. In other words, it is the amount of water that will be released from the snowpack when it melts.
The baseline ratio of rain to snow is 1 inch of rain equals 10 inches of snow. For example, to calculate the snowfall equivalent of 3 inches of rain, multiply 3 by 10 to obtain 30 inches of snow as the baseline conversion.
Slight rain: Less than 0.5 mm per hour. Moderate rain: Greater than 0.5 mm per hour, but less than 4.0 mm per hour. Heavy rain: Greater than 4 mm per hour, but less than 8 mm per hour. … Moderate shower: Greater than 2 mm, but less than 10 mm per hour.
One inch of water or rain is equivalent to 623 gallons per 1,000 square feet.
Multiply the cubic feet by the amount of water per cubic foot, which is 7.48 gallons. In this example, you would multiply 7.48 times 600 to get 4,488 gallons of water.
Wet versus dry snow. There is more water in wet snow than in dry snow. This will change the number of hours it takes with temperatures above freezing for it to melt. … This is a bit more obvious as the further the temperature is above freezing, generally the faster it will melt.
In fact, snow can fall at temperatures as high as 50 degrees. Most residents of the northern United States have probably seen 40-degree snowfalls before, but snow at temperatures greater than 45 degrees is hard to come by. … When moisture overlaps with below-freezing temperatures at cloud level, snowflakes can form.
