The four seasons climate in Alps.

Let me help you. We just talked about o(∩_∩)o in geography class. ...

Climate:

The location of the Alps, as well as the great differences in elevation and orientation of the mountains, not only make the climate between these different small mountains, but also make the climate within a specific small mountain range very different. Because the Alps are located in central Europe, they are influenced by four major climatic factors; Mild and humid air flowing from the west to the Atlantic Ocean; There is cool or cold polar air moving down from northern Europe; The continental air mass controls the east, which is dry and cold in winter and hot in summer; There is warm Mediterranean air flowing north in the south.

The disparity between temperature and annual precipitation is related to the physical geography of Alps. The bottom of the valley is particularly striking because it is warmer and drier than the surrounding highlands. Altitude 1, 524 meters (5,000 feet), almost all precipitation in winter is snow, with an average snow depth of 3? 10m (10? 33 feet) or 10 meters above sea level, 20 12 meters (6,600 feet). Snow lasts from the middle of 1 1 until the end of May. Usually, mountain roads are blocked by snow. In the mountainous areas along the Mediterranean Sea, the average temperature in the valley bottom is -5+10? 4℃(23? 39℉), even as high as 8℃(46℉), the average temperature in July 15? 24℃(59? 75℉)。 Inverse temperature rise is very common, especially in autumn and winter; This valley is often shrouded in dense fog and dreary air for days on end. At these times, places above 1 1,006 meters (3,300 feet) may be warmer and more sunny than low-lying valleys. Gale weather may have obvious effects on weather and local microclimate.

Can the foehn last 2? Within 3 days, the wind direction can be south-north or north-south, depending on the track of the cyclone. This air mass burning wind is cooled when climbing to the top of the mountain, bringing rain or snowfall and slowing down its cooling speed. When this relatively dry air falls on the leeward side, the air heats up at a constant speed due to compression, so the temperature of the air at this time is higher than that at the same height when it begins to flow upward. In the disaster-stricken area, the snow soon disappeared.

Avalanches are a great natural force; 165438+during the period from the end of June to the beginning of June, avalanches are frequent dangers. Avalanches not only cause extensive damage, but also are important catalysts for erosion, because they bring a lot of rocks from the hillside to the bottom.
