Read the graphic materials and complete the following requirements. Xiao Ming and Xiao Liang, who live in Chengdu, discovered during their extracurricular research on "finding the best place to avoid the cold" that there is "Baili Steel".

(1) From the data, the average temperature in Panzhihua in January is 13.6℃ (7.7℃ in Kunming and 5.5℃ in Chengdu). It can be seen that compared with Kunming and Chengdu, the average temperature in Panzhihua in January (winter) is higher. From Figure 7a, we can see that Panzhihua's latitude is higher than Kunming and lower than Chengdu, so latitude is not an important factor. From Figure 7b, we can see that Panzhihua is located in a mountain canyon, so the terrain is the main factor that affects Panzhihua's higher winter temperature. The canyon Topography, the cold air from the north is not easy to enter in winter; the air flow sinks and heats up, which leads to higher temperatures. This question is to examine the factors that affect the temperature, mainly including latitude, land and sea location, ocean currents, topography, and distance from the source of winter winds. etc. The knowledge points will be examined in more detail.

(2) Based on the above questions, we can infer the weather characteristics based on the higher temperatures in Panzhihua. The weather characteristics can include cloudy, sunny, rainy and snowy, temperature and pressure, and wind speed. Wind direction, indicating the angle description of weather conditions.

(3) It belongs to the argumentation type question and belongs to the fourth aspect of the assessment objectives and requirements in the "Examination Syllabus": argumentation and discussion of geographical issues. The goal is high, but. Questioners can simplify the complex and reflect this requirement with easier questions. Analyze the doubts about air quality from the natural and man-made perspectives; Baili Steel City shows that industry, especially heavy industry, emits a lot of pollutants, and urban traffic emits exhaust gas. ; Located in a high mountain canyon, the air is not easy to diffuse, and pollutants accumulate to cause pollution.

So the answer is: (1) Due to the terrain, it is less affected by the cold air (cold wave) from the north in winter. ;

It is located in the valley of the river (Jinsha River), with high mountains and deep valleys, where downdrafts prevail, and the airflow heats up during the sinking process.

(2) Most sunny days, few clouds and rain, and strong winds. Weak, the temperature is higher and more stable (small fluctuations)

(3) The steel industry, other industries, urban traffic, etc. emit a large amount of waste gas; (high mountains and deep valleys) the terrain is relatively closed, with downdrafts and stable air (prone to temperature inversion), which is not conducive to the diffusion of pollutants in the air (therefore, the air quality is poor and not suitable for vacation)
