Question

В Республике Беларусь, как и во всех странах Северного полушария, самая высокая среднемесячная температура бывает в июле, а самая низкаяв январе. Почему же не в июне.когда высота солнца над горизонтам самая большая и дни самые длинные, и не в декабре, когда солнце стоит над горизонтам наиболее низко и дни самые короткие? 2. Известно, что с высотой температура воздуха понижается. Однако в горах северо-восточной части Сибири зимой эта закономерность часто нарушается: на вершинах горных хребтов температура воздуха значительно выше, чвем в межгорных котловинах. Как вы думаете, почему?

Temperature Variation in Belarus and Northern Hemisphere

In the Republic of Belarus, as in all countries in the Northern Hemisphere, the highest average monthly temperature occurs in July, while the lowest occurs in January. One might wonder why this is the case and not in June, when the sun is at its highest point and the days are the longest, or in December, when the sun is at its lowest point and the days are the shortest.

The reason for this temperature variation is primarily due to the lag in heating and cooling of the Earth's surface and atmosphere. Despite the longest days and the highest position of the sun in June, the Earth's surface and atmosphere take time to heat up, resulting in the highest temperatures occurring in July. Similarly, in December, although the sun is at its lowest point and the days are the shortest, the Earth's surface and atmosphere still retain heat from the summer months, resulting in the lowest temperatures occurring in January.

This phenomenon is known as seasonal lag, where the peak temperatures lag behind the peak solar insolation, and the lowest temperatures lag behind the lowest solar insolation. The delay in heating and cooling of the Earth's surface and atmosphere causes the highest and lowest temperatures to occur after the solstices.

Temperature Variation in Northeastern Siberian Mountains

In the northeastern part of the Siberian mountains, particularly in winter, the regular decrease in temperature with altitude is often disrupted. The temperatures on the mountain peaks are significantly higher than in the intermountain basins. This phenomenon can be attributed to several factors.

One possible explanation is the temperature inversion, where a layer of warm air traps cooler air near the surface. In mountainous regions, cold air tends to settle in the valleys, while warmer air is trapped above, leading to higher temperatures at higher altitudes.

Additionally, the topography of the region plays a crucial role. The orientation of the mountain ranges and their interaction with prevailing winds can create microclimates, leading to variations in temperature. For example, foehn winds, which are warm and dry winds that descend down the leeward side of a mountain range, can significantly increase temperatures in certain areas.

Furthermore, the presence of snow cover can also influence temperature variations. Snow-covered valleys can experience lower temperatures due to the insulating effect of the snow, while exposed mountain peaks may receive more direct solar radiation, leading to higher temperatures.

These complex interactions of topography, wind patterns, and snow cover contribute to the irregular temperature distribution in the northeastern Siberian mountains during winter.
