What do you think of the southeast and northwest at night?

Question 1: How to distinguish the southeast, northwest and the sun during the day? Sunrise in the east in the morning, sunset in the west in the evening, and noon in China, which is just south of the central area. Watch the moon at night. Although the moon rises in the east, it rises at different times because the positions of the sun, the earth and the moon are constantly changing. On the first day of the lunar calendar, the moon rises and sets with the sun, so we can't see the moon. In the first half of the lunar calendar, the moon rises around noon. We can see the process of the moon setting in the first half of the night, when the moon was in the west. On the fifteenth day of the lunar calendar, you can see the moon rising on the first night and setting on the last night. In the second half of the lunar calendar, the moon rises around 12 midnight. We can see the process of the moon rising in the middle of the night, when the moon is in the east.

Question 2: How to distinguish the stars and the moon in the southeast, northwest and northwest at night?

Question 3: How to distinguish between southeast and northwest on cloudy days and at night? Look at the tree (except with a compass): the thick side is south and the thin side is north. Look at the sun in the morning: facing the sun, the front is east, the back is west, the left is north, and the right is south. You can tell the direction by looking at Polaris at night. Getting lost in the wild is really troublesome. If you bring a compass, the problem will be solved. But what if there is no compass? Don't worry, nature has prepared many "compasses" to help people find their way. The first compass is the sun. We live in the northern hemisphere. Except in the south of the Tropic of Cancer, the sun always shines from the south. In this way, the north-south direction can be easily determined. We all know that the sun rises in the east and sets in the west. The sun rises in the east in the morning, sets in the west at night, and is in our south at noon. However, you should not apply this method dogmatically. If you are in the southern hemisphere or between the Tropic of Cancer, the situation is another matter. The second kind of compass is the moon. On the third and fourth day, the crescent moon, the sunset is low in the west; On the eighth day of the seventh lunar month, the sun just went down, just above our heads. In half a month, as soon as the sun goes down, the moon rises in the east. The direction of the moon at night is: the first quarter moon, in the south at 6 pm, and in the west at 12 pm. The full moon (14- 18) is in the east at 6 pm, in the south at 12 pm, and in the west at 6 am the next day. First quarter moon, in the east at night 12, and in the south at 6 o'clock the next morning. The third kind of compass is Polaris. Polaris is the best compass, and its direction is due north. But how to find Polaris? In fact, it is easy to find the familiar Big Dipper. The Big Dipper is like a water spoon. When the two stars on the side of the water spoon are stretched to about 5 times, there is a brighter star, the Polaris. On the opposite side of Polaris, there is also a constellation Andromeda, shaped like the English letter W, which can also help us find Polaris. Around 8 pm, if February-August, February 2- 10/October, you can use Ursa major to find Polaris, and Cassiopeia is better. The fourth kind of compass is trees. This method is also very simple. For example, north of the Tropic of Cancer, the sun shines from the south, and the trees in the south get more heat from the sun than the trees in the north. Therefore, the branches of independent trees grow luxuriantly to the south and sparsely to the north. It can also be distinguished by tree rings. These rings face south in width and north in density. Because the south grows faster than the north, the annual ring interval is wider. The fifth kind of compass is snow. Similarly, take our northern hemisphere as an example. The snow on the southern hillside is denser and more granular. The snow on the northern hillside is softer and drier. When the snow melts, the snow on the south hillside melts more easily than the snow on the north hillside. With the above methods, you don't have to worry about getting lost.

Question 4: If you get lost, how can you tell the difference between southeast and northwest? What if it's night? In the wild, if the night sky is clear, you can determine the direction by the stars or observe the growth of trees. There are many leaves in the northern hemisphere on the south side. Houses can be observed in the urban area, and balconies are all on the south side.

Question 5: How to distinguish between southeast and northwest in real life? If you are not in the wild, you can look at the direction of the house. Generally, the balconies of houses and buildings face south.

If you are in the wild, you can follow the following methods: the south side of the independent tree is lush and the north side is sparse; The north side of the rock is covered with moss, and the south side is dry and bare; The hard-to-melt part of snow always faces north; Ant cave faces south; If it is a starry night, look sideways at the Big Dipper arranged like a spoon, and follow the "spoon handle" to find the bright Polaris indicating the direction from south to north.

Question 6: How to tell the difference between the southeast and the northwest Nowadays, many people are only familiar with the southeast and the northwest near them, but they can't tell the difference when they arrive in cities or mountainous areas. And some friends, who only know the map from north to south, left to west and right to east, are at a loss in real life.

Many people know that the sun rises in the east and sets in the west, and then you can know the north and south according to the left, west, right, east, upper north and lower south.

Then, in the night without sun, stars and moon, on cloudy days, rainy and snowy days, how can we tell the difference between southeast and northwest? Signs in the city will indicate the southeast and northwest, so what about non-urban places or the wild without signboards? How to distinguish between southeast and northwest? For example, you can tell the direction by leaves, rivers and crops. )

1, Polaris Polaris the best compass, and the direction of Polaris is due north.

2. The Big Dipper Ursa is like a huge spoon, which is easy to find in the clear night sky. From the direction of the extension line of the two stars on the spoon, there is a brighter star, Polaris, which is about five times apart, in the true north direction.

3. The dense side of the tree and moss crown should be the south, and the sparse side should be the north. The truth of moss alternates with it. In addition, you can also determine the direction by observing the tree rings. The sparse side of tree rings faces south and the dense side faces north.

4, the melting of snow, the place where the snow melts first must be facing south.

5. Observe the Moon The moon itself does not shine, but it reflects sunlight. When it orbits the earth for more than 28 days, the shape of the moon will change with the earth because of its different relative positions. If the moon and the sun are located on the same side of the earth and can't see the moonlight, it's called "new moon" (A)-then, with the counterclockwise revolution, the sun gradually reflects, and the moon gradually becomes round. The full moon and the sun are located on both sides of the earth (B). At this time, the moon looks big and round, and then it gradually becomes deficient and repeats itself. This can be used to determine the direction. If the moon rises before the sun, the illuminated side is in the west. If the moon rises after the sun, the "glowing" side is in the east. This method seems simple and clear, but it doesn't mean that the moon can be used to tell the east-west direction all night.

6. Observe the ant's cave. Most holes face south.

7. Where there are many rocks, you can also find an eye-catching rock for observation. The mossy side of the rock is the north side, and the dry and bare side is the south side.

8. You can also use a watch to tell the direction: divide your time by 2, and then aim the quotient at the sun. The direction indicated by 12 on the dial is north.

9. Using features, the following features can help us identify the direction: House: Houses generally face south, especially in the north of China. Temples: Temples generally have doors facing south, especially the main halls in the temples. Trees: The south-facing side of trees is usually lush, brightly colored and smooth, while the north-facing side is the opposite. At the same time, there may be moss on the trunk facing north. Outstanding features: such as walls, ridges, stones, etc. The base on the north side is wet and bryophytes may grow. Concave features: such as rivers, ponds and pits. , and its northern edge (bank and edge) is the same as the edge that highlights the feature.

10, other methods. 1. Use the characteristics of nature to determine the direction. Without topographic maps, compasses and other equipment, we must learn to use some characteristics of nature to determine the direction.

First of all, the sun is the most reliable compass.

We know that the sun moves from east to west, while the shadow moves from west to east. For example, at 6 o'clock in the morning, the sun rises in the east, and the shadows of all objects fall to the west; By noon 12, the sun is due south and the shadow points to the north; By 6 pm, the sun is due to the west and the shadow points to the east. So the direction can be roughly determined by the shadows of the sun and objects.

As the saying goes: "immediate", use a pole (straight pole) to make it perpendicular to the ground, and put a stone at the vertex A of the pole shadow; About 10 minute, when the shadow vertex of the column moves to B, put another stone to connect the two points A and B into a straight line, which points to the east-west direction. The direction perpendicular to the AB line is the north-south direction, the end facing the sun is the south, and the opposite direction is the north (Figure 5) ... > >

Question 7: How to distinguish between southeast and northwest, and how to distinguish between southeast and northwest?

Nowadays, many people are only familiar with the southeast and northwest of their nearby places, but they can't tell them apart when they arrive in cities or mountainous areas. And some friends, who only know the map from north to south, left to west and right to east, are at a loss in real life.

Many people know that the sun rises in the east and sets in the west, and then you can know the north and south according to the left, west, right, east, upper north and lower south. There is another way, using an analog watch, the hour hand is aimed at the sun, and the middle position between the minute hand and the hour hand is due south!

Then, in the night without sun, stars and moon, on cloudy days, rainy and snowy days, how can we tell the difference between southeast and northwest? Signs in the city will indicate the southeast and northwest, so what about non-urban places or the wild without signboards? How to distinguish between southeast and northwest? For example, you can tell the direction by leaves, rivers and crops. )

This method seems simple and clear, but it doesn't mean that the moon can be used to tell the east-west direction all night.

6. Observe the ant's cave. Most holes face south.

Question 8: How to tell the difference between southeast and northwest? If you don't know the southeast and northwest outside, the best way to know is to look at the road signs. Generally, N refers to the north, S refers to Guide, E refers to the east, and W refers to the west.

If there is wind, it depends on which direction it is blowing. I remember that in summer, the southeast wind blows and the front faces the wind. Both hands extend at a 90-degree angle, with the left hand facing east and the right hand facing south; In winter, the northwest wind blows, which is the wind from Siberia. The method is the same as above, the left hand faces west and the right hand faces north;

If there is a residential building nearby, it will be easier. The doors are all facing north and the balconies are all facing south, which can explain why sometimes the houses on the roadside are diagonally parallel instead of parallel to the road. That's because the road is not necessarily east-west or north-south, but the door of the house must face north, which has been measured by professionals, so this method is the most practical (mainly recommended) whether it is day or night;

And watching the sun. The general direction is east in the morning and west in the afternoon, but it is only the general direction.

In addition, there are stars at night, the inclination and luxuriance of trees, dry shadows, the flying direction of geese and so on. , but they are not very practical. Personally, I think the most practical thing is to look at the residents' houses, which is the most accurate and convenient way. These doors all face north. You just need to remember the formula of "going up north and down south, left west and right east". No matter where you are, you can tell the direction.

Question 9: How to divide the night between east, west, north and south? Most houses have balconies facing south.
