Hello, I'm an expert in meteorology with a focus on weather phenomena. Let's delve into the question of whether it's "too cold" or "too cold" to generate snow. The phrase "too cold" is often used colloquially to express that the temperature is excessively low for a certain activity or condition to occur. In the context of snowfall, it's more accurate to say that the atmosphere must be at a certain temperature range for snow to form, rather than simply being "too cold."

Snow forms when the atmospheric conditions are just right. The process involves the cooling of air to the point where water vapor condenses into ice crystals, which then aggregate to form snowflakes. The temperature plays a crucial role in this process. It's not just about the air being cold; it's about the air being cold enough to allow for the formation of snow, but not so cold that it inhibits the process.

The reference content you provided states that "But the atmosphere must contain moisture to generate snow--and very cold air contains very little moisture. Once the air temperature at ground level drops below about -10 degrees Fahrenheit (-20 degrees Celsius), snowfall becomes unlikely in most places." This statement is partially correct but requires some clarification.

It's true that moisture is necessary for snow to form. However, the assertion that very cold air contains very little moisture is not entirely accurate. Cold air can hold less moisture than warm air, but it doesn't mean it contains "very little" moisture. The actual amount of moisture in the air can vary greatly depending on the specific conditions.

The temperature threshold mentioned in the reference is also a bit misleading. While it's true that extremely low temperatures can limit the formation of snow, it's not a hard and fast rule that snowfall becomes unlikely below -10°F (-20°C). Snow can and does occur at temperatures lower than this threshold. The key factor is the presence of moisture and the right atmospheric conditions, which can sometimes occur even at very low temperatures.

In summary, the phrase "too cold" is not the most scientifically accurate way to describe the conditions necessary for snowfall. Instead, it's about the right balance of temperature and moisture. Snow is more likely to form when the temperature is at or below freezing, and there is sufficient moisture in the air. Extremely low temperatures can limit this process, but they don't automatically prevent snowfall.

Now, let's move on to the translation of the above explanation into Chinese.
