The following is the description of the weather in the stories "The Water Margin" and "Taking Suochao on a Snowy Day in Song Gongming". Please answer this question after reading it. "Now is the day, there is no crystal lamp during the day. (1) According to materials such as "horseshoe is frozen, armor is like ice" and "heavy snow falls in one day", it can be judged that there is cooling and heavy snow in this area. According to this feature, it can be judged that the material describes the cold front transit.

(2)(3)(4) Strong winds, rain, snow and cooling weather often occur when cold fronts cross the border. "The next day, the clouds were brought up behind, and the sky cracked badly"; "The heavier the cloud that night, the tighter the wind color. Wu Yong looked out of the account, rolled into a ball early, and it snowed all day ",which clearly described the weather conditions when the cold front crossed the border." After finding this time node, according to the time sequence of weather changes, it is not difficult to judge the time period before and after the cold front transits.

(5) Both the fast-moving cold front and the slow-moving cold front are cold fronts, but the moving speed of the cold front is different due to the different forces of the cold air mass. Comparatively speaking, the weather changes caused by the fast-moving cold front are more intense, and extreme weather such as strong wind cooling (cold wave), heavy rain and blizzard are more likely to occur when crossing the border, and the cooling is more obvious after crossing the border, while the slow-moving cold front forms persistent precipitation weather with long duration but less intensity.

So the answer is:

(1) This passage is about cold front weather.

(2) "This is a day ... armored as ice"

(3) "The next day ... it snowed all day"

(4) "The snow ... didn't reach the horse's knees"

(5) The cold front moves very fast.

First, the weather process is very short. Second, the intensity is very high, as evidenced by "strong wind ... heavy snow"
