Test analysis:

Question 1: the snowfall caused by the Great Lakes effect depends on the following factors: the temperature difference between the cold air mass and the water surface. When the temperature difference is large, the higher the water temperature, the lower the temperature of the cold air mass, the more condensed water vapor and the more snow. The temperature is low and the water temperature is high in each period. But (3) the water temperature and air temperature are above 0℃, so it is not easy to snow; ① ④ Comparatively speaking, when the water temperature is above 0 degrees Celsius, the evaporation is more intense, which is more in line with the meaning of the question.

Question 2: The Great Lakes effect refers to the phenomenon that cold air meets a large area of unfrozen water surface (usually a lake) and obtains water vapor and heat energy from it, and then forms precipitation, snowfall and fog on the windward bank of the lake. So this process is similar to the meeting of cold and warm air masses. Specifically, the warm front is the precipitation formed when the cold air mass meets the strong warm air and the warm air mass climbs upward. The principle of the two is similar. The cold front is that the warm air mass meets the strong cold air mass, which is different from the Great Lakes effect.
