1.First of all

Analyzing junior high school science textbooks in Japan, extratropical cyclones and precipitation areas associated with fronts are depicted only on the cold air region side of the fronts. The content of these textbooks is almost the same as that of the 1970s textbooks, causing misconceptions about the mechanism of heavy rain disasters that occur during the flood season. Students who go on to science are less likely to take earth sciences in high school due to university entrance examinations, and the last opportunity to study the meteorological field is in the second year of junior high school.

2. Student misconception cases related to weather disaster prevention

Kato (2013) said, "In the cyclone model have learned in junior high school, cumulonimbus clouds occur on the cold front, and there are no clouds in the area between the cold front and the warm front. Heavy rains are often observed in the area between the cold front and the warm front.　Meteorological officials understand that warm and humid air is likely to occur and heavy rain disasters are likely to occur, but in junior high school textbooks. Since it is described as an area where it does not rain, it cannot be understood that it will rain heavily.

3. Meteorological learning that does not cause misconception

An analysis of student misconceptions about meteorology revealed that learning in the meteorological field was not systematic and it was difficult to understand the wind direction from weather maps. By emphasizing the fact that the isobars of the weather map represent the wind direction and learning the wind direction by tracing the isobars of the weather map and adding arrows, the students could immediately understand the warm air advection and cold air advection. It is necessary to understand that the place where warm and humid air flows is a place where the atmospheric condition where cumulonimbus clouds develop is unstable
