#### 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.

Wet snow not only sticks to everything, but **it is also heavier than dry snow**. One inch of wet snow can contain 2 to 3 times more water than one inch of dry snow, making it that much heavier.
## How is inches of snow measured?

The specific weight of water is **62.43 pounds** (avoirdupois) per cubic foot.

How to Measure: Push the yardstick straight into the snow, perpendicular to the ground, until the yardstick reaches the snow board. Record the measurement to the **nearest tenth of an inch**; e.g. 3.3 inches. Keep track of all your measurements for the duration of the storm so you can report the storm total amount.
## Is 1/10th of an inch of ice a lot?

## What is meant by equivalent water depth of snow?

## How do you convert inches of rain to snow?

## Is 0.05 in of rain a lot?

## What is the Kuchera snow ratio?

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.

The **10:1 ratio** snowfall products exist primarily as a very conservative estimate for legacy purposes, and because they are painless to compute. For certain datasets, we may not be able to compute Kuchera, leaving 10:1 as the only practical option.
## How many gallons is an inch of water?

One inch of water or rain is equivalent to **623 gallons per 1,000 square feet**.

Every square foot of roof space collects . **6 gallons** of water in a 1 inch rainfall.
## How many gallons is 600 square feet?

## Does rain melt snow faster?

## Can it snow at 40 degrees?

## What temp does snow melt?

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.
