Do you know what the climate of several cities in the south of the Pearl River Delta is different?

Let's talk about why these three places are quite close, but the difference is still quite big. Different latitudes:

Although the latitude difference between Nanjing, Shanghai and Hangzhou is basically 1, this slight difference sometimes has a great influence. In common language, the orange in Huainan is orange and the orange in Huaibei is bitter orange. The different visible positions have certain influence on the climate.

First, without considering other factors, only considering the relationship between temperature and radiation, we might as well analyze it this way: from our daily experience, it is also colder in the north. Although there is only a difference of 1, the climatic conditions are cumulative.

It is this difference that has been changing the climate characteristics of these three regions for thousands of years. Different terrains:

Terrain is also one of the important factors that form different climate characteristics. Although there are many plains and hills in the middle and lower reaches of the Yangtze River, these three places

There is little difference in terrain. But if you analyze it carefully, it is quite interesting.

Nanjing is surrounded by mountains on three sides and water on one side. Shanghai is near the sea, while Hangzhou is low and watery.

Each place has its own topographical features, although generally speaking,

Generally speaking, it is almost the same, and the three places are different in micro-scale meteorological conditions. Diffusion conditions of pollutant condensation nuclei,

The evaporation of water vapor, the obstruction of wind and the difference of underlying surface will all affect the local climate. Urban underlying surface is different:

In recent years, many meteorologists are studying the impact of urbanization on climate. The central and eastern regions of China have developed since the reform and opening up.

One of the fastest growing areas. The change of urban underlying surface can be said to change every few years. ?

Second, these three cities, especially Shanghai, are dominated by cities. The greening of the three cities is different, and the distribution of buildings in urban areas and county towns is also different.

The roughness of the underlying surface is also different. These are all important factors that affect urban micro-meteorology.

The difference of urban underlying surface, coupled with the different topography of the three places, also contributed to the different climate of the three places.

Finally, the answer is to remind you. In daily life, we often compare "climate" and "weather" together. This is also

Inevitably, because in our daily life, our personal feelings about "weather" are more intuitive. For example, 20 15, the national average winter gas.

This is a warm winter, but most people think it is very cold because of the cold wave of overlord.

Similarly, the so-called climate differences in Nanjing, Shanghai and Hangzhou are sometimes just because they are in different parts of a certain weather system, which makes the three places have different performances.

To study the climate state, it is necessary to use at least 30 years of accumulated meteorological data for research.

However, I think the climate difference between the three places mentioned by the subject does exist. Generally speaking, the climate in the three places is similar, but

Every city has its own microclimate. I believe that in the future, there will be more Daniel to uncover the mystery of all this!

Third, the best season is roughly from mid-August to mid-February in 65438+, which can be said to be autumn, with less rain and fewer mosquitoes. Autumn is really high.

Cool.

The biggest climate difference between Nanjing and Shanghai is summer. The solar calendar starts in mid-June and goes through the period from July to early August. Summer in Nanjing

It's really a stove. His temperature is very stable. 36 during the day and 33 at night. Wan Li is cloudless and windless on sunny days.

You have nowhere to run, and the air is still.

Shanghai is different. It will be very hot during the day in summer, but it will be hot during the day and easterly winds will blow at night. You will know it after studying geography, because

The specific heat of water is high, so the temperature of the ocean is lower than that of the land in summer. At night, the air pressure on the ocean will be higher than that on the land, and the sea breeze will blow from the sea to the land. Therefore, as long as it is sunny in summer in Shanghai, the east wind will blow every night, and the temperature will drop a lot, with a temperature difference between day and night.

It is relatively large, such as 36 in the daytime and only about 30 degrees at night, which is especially suitable for shopping in Dongxi Street, Nanjing Road and Huaihai Road.

The road or something.

The evening breeze blows gently, which is particularly comfortable. I have lived in Nanjing for 18 years (from Nanjing) and stayed in Hangzhou for almost 10 years. Personal opinion: When I was in Nanjing, I felt that Nanjing was not.

I'm alone. The weather is terrible. It is hot in summer and cold in winter. In this way, it feels like going back to Nanjing after going to school in Hangzhou, alas, the south.

Why is the weather in Beijing so good? It is really comfortable. No blowing, no black. First, pomelo trees can be planted in Nanjing. There will be one or two pomelo trees in many rural areas in the suburbs of Nanjing, but they are generally used for viewing and the fruit is not delicious. ?

Fourth, although Nanjing is located in the warm south of the Yangtze River, its climate is not very good. In spring, from April to May, hot and cold changes greatly, sometimes the day before.

Wear short sleeves and you will get a thick coat when the temperature drops the next day. It is inconvenient to wear clothes and easy to catch a cold. In June after the summer, the long plum rain made Jiangnan

When people collapse, Nanjing will have several storms to watch the sea at this time of year, which is the season when the whole city can't finish boating for a week. enter

In dog days, Nanjing's midsummer can heat people to death, almost exceeding 35 degrees every day, sweating as soon as you go out, sweating as soon as you get up early, and at night.

Above 30 degrees, fun running is difficult. The weather turns cold in September, so 10 should be regarded as the best time in Nanjing, provided there is no continuity.

Autumn rain. After 1 1, Nanjing entered the winter, which was terrible. The temperature is often a few degrees below zero and there is no heating. /kloc-0 There will be two or three heavy snowfalls every year. At that time,

You can enjoy Jinling in the snow later.

The temperature difference between Shanghai, Hangzhou and Nanjing in summer is not very big, but the temperature in Nanjing is the lowest in winter, Shanghai is lower than Hangzhou and Hangzhou is the highest. Although this

The temperature difference between the three places is not very big, about 2 degrees, such as 2 degrees in Nanjing, 4 degrees in Shanghai and 6 degrees in Hangzhou, which is about this scale.

The subtropical monsoon climate is divided according to the climate of planetary wind system, which belongs to the arid area controlled by subtropical high belt, but because of the difference between land and sea.

Different from the temperature and pressure field changes caused by the uplift of the Qinghai-Tibet Plateau, the monsoon circulation changes the circulation system of the upper planetary wind system near the earth and becomes dry.

The continental climate is humid subtropical monsoon climate, and the arid desert scene becomes humid evergreen broad-leaved forest scene. Through thousands.

Man-made influence in 2000 made this area a densely populated and economically developed area in China.

It belongs to subtropical monsoon climate, and it is divided according to the climate of planetary wind system. It belongs to an arid area controlled by the subtropical high belt. However, due to the sea-land difference and the change of temperature and pressure field caused by the arching of the Qinghai-Tibet Plateau, the monsoon circulation changed the circulation system of the planetary wind system in the upper layer near the ground, changed the arid continental climate into a humid subtropical monsoon climate, and changed the arid desert scene into a humid evergreen broad-leaved forest scene. After thousands of years of human activities, this area has become a densely populated and economically prosperous area in China. The main characteristics of the climate in this area are: warm winter and hot summer, obvious precipitation in four seasons and even seasonal distribution.
