Read the latitude and longitude network diagram (as shown in the figure) and answer questions 3-4. The sun shadow at noon at A is the longest time in a year, and the season in Suizhou is the same as that described in the following poem.
According to the latitude and longitude network, the degree of latitude is called latitude. If the latitudes of two adjacent latitudes increase northward, it is the north latitude, which is represented by the symbol N, and if the latitudes of two adjacent latitudes increase southward, it is the south latitude, which is represented by the symbol S. As can be seen from reading the figure, the latitude of point A is 60 N, which is located in the northern hemisphere. In the northern hemisphere, when the sun shadow is the longest at noon in a year, the sun shines directly on the tropic of Capricorn, which is winter in the northern hemisphere.
Suizhou, the hometown of Emperor Yan, is located in the northern part of Hubei Province and belongs to the northern hemisphere. According to the analysis options, A describes the peach blossom in spring, B describes the yellow leaves in autumn, C describes the length of days in summer, and D describes the snow scene in winter.
