A heavy snow. Fill in quantifiers, right?

Wrong. It is inappropriate to use "sudden" as a quantifier of heavy snow, mainly because the word "sudden" is usually used to describe short-term and intermittent weather phenomena, rather than continuous and long-term weather conditions. Heavy snow is a state of continuous snow, so it is more appropriate to use "field" as a quantifier. In Chinese, the choice and use of quantifiers need to be decided according to the context and actual situation. Different quantifiers can express different meanings and emotional colors. "Field" is usually used to describe persistent weather phenomena with certain time and space, such as "a rain" and "a gale". And "array" is usually used to describe short and intermittent weather phenomena, such as "shower" and "gust". Therefore, it is more appropriate to use "a heavy snow" when describing heavy snow, because it can better express the persistence and intensity of heavy snow. If we use "a burst of heavy snow", people may mistakenly think that heavy snow is a short-term and intermittent phenomenon, rather than a continuous and long-term weather condition.
