What is the difference between alpine snow melt and snow melt? Why is the melting period different?

In terms of composition, it should be the same, snow melt water will be higher mountain ice melt water will contain more impurities mountain ice melt water will melt faster than snow melt water because the temperature on the high mountains is lower.

The differences are as follows: 1. The reasons for formation are different.

Melting water from snow and ice. This refers to the snow that is formed by winter snowfall and melts into water when the temperature rises in the following spring, as in the Tohoku region.

and rivers in North China will be replenished by ice and snow melt water in spring, thus forming spring floods. In spring and summer, the temperature is high and the snow melts all year round, and there is a spring flood in spring, and summer and atmospheric precipitation together form a summer flood, which is mostly distributed in the Tianshan Mountains of Xinjiang.

There are areas where there is a lack of coarseness and the temperature is high in summer. Snowmelt is formed due to high summer temperatures.

2. The occurrence of the line is different in season.

Snow melt mostly occurs in the summer when the temperature is high. Seasonal snow melt is distributed in the northeast of China, which is characterized by the spring flood of the river around March, because it is the monsoon area here, so the river will also have summer flood in July, that is, there are two flood seasons a year. Glacial meltwater is in the northwestern region of our country.

The time to resupply is in the summer, because of the high summer temperatures. The rivers here have no supply source in winter and spring, so they are prone to breakdowns. Therefore, it is characterized by the fact that the flow is easy to break in late winter and early spring, and the flood season occurs in summer.

3. The place of occurrence is different.

Snowmelt is mainly distributed at high altitudes; Glacial meltwater is mainly distributed in the North and South poles; Ice and snow melt mostly occurs in Northeast China and North China.

Ice and snow meltwater--- glacier and alpine snow meltwater; The melting is greatest in summer.

Glacial meltwater melts the most --- summer.

Snow melt --- seasonal snow melt, which generally covers snow in winter and melts in spring.

First, the water source is different.

1. Glacier meltwater: the runoff formed by the confluence of glacier ice and snow meltwater on the glacier surface into the river.

2. Ice and snow meltwater recharge: In the alpine areas in the basin, the recharge of permanent snow or glacial meltwater.

Second, the role is different.

1. Glacial meltwater: The glacial meltwater produced by glacial melt has a recharge effect on the river. Many of the world's great rivers are formed by the recharge of glacial meltwater.

2. Ice and snow melt water supply: due to the temperature, crops can only grow in summer for half a year, when a large amount of ice and snow melt water, timely irrigation water, which is very beneficial to agricultural and animal husbandry production. The snow melts and recharges the river.

Alpine ice and snow meltwater:In fact, the process of ablation is from the winter snow line to near the summer snow line. There is both glacial retreat and snow retreat; The predecessor of the glacier was also compacted granular snow.

Because of the higher altitude or higher latitude, the greatest melting in this area occurs in summer.

Seasonal snow meltwater:It generally occurs in plains or plateaus, with the lowest altitude below 0°C in winter and above 0°C in spring and summer. For example, the northeast of our country and the Siberian region of Russia.

The low temperature in winter is conducive to the accumulation of snowfall; Spring and summer temperatures are high, and the snow is completely melting.

The biggest difference, meltwater**. The former has both glaciers and snow; The latter only has snow that cannot survive the summer.

The big mistake upstairs too!!

The water supply method is different, the snow melt water supply is the snow melt supply, spring occurs, no matter where it is, as long as there is enough snow on the line, such as China's northeast, Russia, etc. have sufficient snow melt water supply, forming a spring flood.

Glacier meltwater recharge is the melting of glaciers in itself due to the hot summer to produce water, mostly in alpine areas, such as the Qinghai-Tibet Plateau, Kunlun Mountains, Tianshan Mountains, and generally does not appear in the polar regions (you go to check the map).

I am one or two in the grade of physical geography, and I am proficient in these, believe me.

Actually, I think the landlord may have made a mistake.

Because when we talk about the method of replenishment, we are generally talking about seasonal snow melt recharge, and it is easy to understand this way.

As the name suggests, the snow is formed in the northern region in the winter due to low temperatures, and then the snow melts as the temperature rises.

Glacier meltwater recharge refers to the Qinghai-Tibet region or other places at higher altitudes, where the glaciers are cold all year round, and then melt some of the recharge river water as the temperature rises.

The snow meltwater flood season is mainly in the Spring Festival, and the glacial meltwater flood season is mainly in the summer.

The latitude and altitude of the regions in which they are located are different. Snowmelt water recharge occurs at high altitudes, such as the Tibetan Plateau. Glacial meltwater recharge occurs near the poles.
