How to distinguish the southeast and northwest in the desert, please thank you

Take advantage of the sun In winter, the sunrise position is south-east and the sunset position is south-west; In summer, the sunrise position is north-east and the sunset position is north-west; Around the spring and autumn equinoxes, sunrise is due east and sunset is due west. As long as there is the sun, you can use the watch to discern the direction. Read the moment in 24-hour format and divide the number of hours by two to get one hour.

Place the watch horizontally on your hand or on the ground, so that the watch is aligned with the direction of the sun at this moment, and the direction of the watch at 12 o'clock is north, and the direction at 6 o'clock is south. Immediately, a pole is erected vertically on the ground, the shadow points northwest in the morning, and the shadow points northeast in the afternoon, and the shadow is shortest at noon, when the shadow points due north. Make use of the stars Aim for the North Star.

First of all, find the spoon-shaped Big Dipper, and extend the interval between the two stars on the spoon C by 5 times, and then you can find the North Star in this straight line, and the direction of the North Star is due north. Use features to determine the orientation. Large, free-standing trees usually have dense foliage and smooth bark on the south side, and sparse branches and rough bark on the north side.

The south side is usually grassy, and the north side is moist and mossy. For buildings and mounds, snow melts slowly in the north, while in depressions such as earth pits, the opposite is true. The doors and windows of the larger temples in northern China, the main entrance of the pagoda and the independent houses in the countryside are mostly open to the south.

The northern edge of the forest glade is more grassy. The annual rings of the stump section are generally spaced at a large interval in the south and a small interval in the north. In the grasslands of northern China, there are many northwest winds in desert areas, and many snow dragons and salons are often formed near the grass, with large heads and small tails, and the direction of the head is northwest.

It's okay to look at the sun during the day and the moon at night.

There are two tips:

1. Look at the road signs, there are generally road signs at the intersections.

2. Look at the order of the house number.

The order of house number numbers is generally determined according to the direction of the road. The roads run east-west and are numbered from east to west; Roads run north-south and are numbered from south to north; northeast-southwest, numbered from northeast to southwest; Southeast-northwest direction, numbered from southeast to northwest. Among them, if there is vacant land to be built on both sides of the road, an empty number should be reserved according to 3-5 meters; If a new door is not reserved for an empty number, it shall be numbered in order under the existing house number.

The odd and even numbers of the house number are oriented in the order of the house number, and are numbered according to the left single and right double.

The second method is suitable for determining whether the road is east-west or north-south, depending on the size of the house number, you can determine whether it is east-west (knowing that the road is east-west) or north-south (knowing that the road is north-south).

I don't know either, but there are two ways.

1 is to bring a compass

2 That's because our school is boxy, and I'm going to move the school over when I go.

It's really weird! Wherever others go, they immediately know that I can read the sun in the early morning and evening. Other times I feel like the sun is overhead.

Look at the sun, we're in the northern hemisphere, so the sun is in the south. It's just that the sun is in the east in the morning and the west in the afternoon, so you just need to practice a few more times.

Find someone to ask.

If your sixth sense is good, you don't have to divide it, and you can go by feeling.

In Beijing, you won't be able to distinguish between east and west, north and south, and you will be convinced!! Just use the compass invented by our ancestors, not to mention that you can't understand the compass.

I don't distinguish between east and west, but on a sunny day, I can tell because there is a sun, and when it is cloudy.

Do you want to divide this? You don't feel it?

On a clear day, it is easy to know the east and west according to the sunrise and sunset, and you can also judge the direction. However, it can only be roughly estimated, and there are several methods for more accurate determination:

1) Watch direction finding. "Half of the hours are for the sun, 12 refers to the north", generally between 9 a.m. and 4 p.m., you can quickly identify the direction, with half of the time pointing to the sun, 12 hours is the north, such as 14:40 in the afternoon, half of which is 7:

20, the hour is directed to the sun, then 12 refers to the north, or the watch is flat, the hour is aimed at the sun, and the reverse extension direction of the hour hand and the bisector of the 12th scale is the north; Or put a stick vertically on the watch** and turn the watch so that the shadow of the stick coincides with the hour hand, and the bisector between this time and the 12th hour is north.

It must be noted that when determining the direction, the watch should be flat; It should not be used around noon in the area between 20 and 30 degrees north latitude.

2) Direction finding in the sun. A stick is erected on the ground, and the shadows of the sticks move with the position of the sun, and these shadows are shortest at noon, and the line at the end of it is a straight line, and the vertical line of the line is north-south.

Draw a series of concentric circles on a piece of drawing paper of 50 to 50 cm, the radius of the concentric circles increases by 1 cm, nail to a flat plate and fix it horizontally, inserting a thin steel needle or needle 12 15 cm long vertically into the center of the circle. When the position of the sun changes, the endpoints of the shadow will always intersect with concentric circles to plot these points, and then connect two points on the same circle in a straight line, and connect the points of these lines with the center of the circle, this line is the north-south direction line, and the direction of the top of the arc is north.

Navigation is a way to distinguish between southeast and northwest.

Teach you how to quickly distinguish, southeast, northwest, and never be a road idiot again.

The sun rises in the east and then separates according to the method of going up and down to the south, left to the west, and to the right to the east.

The direction in which the sun rises is east. The direction of the North Star is north.

Wake up in the morning and face the sun, east in front, west in the back, north on the left, and south on the right.

It's in elementary school textbooks.

There is also an article in the elementary school textbook called "If You Get Lost in the Forest", and there are many of them!

Sun, compass.

If you can't do it, buy a watch, and you have to have a compass.

Watch the sun during the day and the North Star at night or buy a compass.

The sun rises in the east and the sun is in the south.

Look at the sun during the day and the moon at night.

Wake up in the morning and face the sun, east in front and west in the back, north on the left and south on the right.

There is also the sun to watch, early in the morning, the sun is in the east, noon is in the south, afternoon and evening is in the west, I wish you a pleasant day!

Between 9 a.m. and 4 p.m., you can quickly discern the approximate direction by following the following phrase: "The hour is half a pair of the sun, and '12' refers to the north." If it is 9 a.m., it should be directed towards the Sun at 4:30 a.m.; For example, at 2:40 p.m. (i.e. 2:40 p.m.), the sun should be directed at 7:20 p.m., and the direction of the "12" is north.

To improve the accuracy of the judgment, a thin needle or straw stick can be erected at the position of "half the hour" and its shadow can pass through the center of the dial.

In addition to looking at the sun, you can also know by looking at the direction of the big river, the river flows eastward... Then according to the up, north, down, south, left, west, right, east.

The hour hand is facing the sun after dividing the local time by 2, and the dial is due north at 12 o'clock. Limited expressive skills. Let's give an example.

For example, if it's 4 p.m. (4 p.m.) and you face the sun at 8 o'clock, the direction of 12 o'clock on the dial is due north. Be sure to use local time. For example, in Xinjiang, Beijing time is usually used, and when measuring the bearing, it is necessary to subtract two hours from the Beijing time.

The easiest way is to look at the direction in which the sun rises and sets, rising in the east and descending in the west, and then according to your own position, up and down, south, left, west, right and east.

With a watch can be discerned, if not in mind can imagine a clock dial.

A watch with a hand that points the hour hand to the sun at ten o'clock in the morning. Then find the angular bisector of the hour and minute hands, i.e., north and south.

Use a compass.

Look for iconic buildings.

Looking at the sun on a sunny day, you can see the solar water heater in the city, and the pipe is facing the south.

Look at the road signs, generally there will be directions on the road signs.

Depending on your geographic location, there are many ways to do this. For example, urban areas can be based on road signs, in the field according to leaves, and so on.

Depending on the direction of the gate. China generally sits in the north and faces south.

If you have a fine metal such as a needle, you can tie a thread between the needles and rub the needles against the cotton fabric to make it static. Hanging and placed, you can indicate the south and north.

If necessary, you can wait for daylight. At noon, the sun is in the southern direction. You can't die in one night.

During the day, the position of the hour hand of your watch points to the sun, the hour is divided by half, and the corresponding scale is north, opposite is south, south and back to north, left east right west. For example, 4 p.m. is 16 p.m., 4 p.m. points to the sun, and 8 p.m. is due north on the surface.

It's very simple, look at the map, go up and down the south, left west and right east.

I really can't buy a compass.

The leaves are not accurate, and if the weather is good, it depends on the sun.

Hold a compass and borrow technology.

In addition to using a compass to determine direction, we can also use a watch to measure direction. It's not very precise, but it's practical.

The prerequisite for this method is that there is a sun in the sky.

Method 1: Divide the current time by 2 and align the resulting quotient with the Sun. The 12 opposite directions on the dial are north.

For example, it's 8 a.m., divide by 2, the quotient is 4, and the 4 on the dial is aligned with the sun, and the direction 12 is north. If it is afternoon, it should be calculated using the 24-hour timekeeping method.

Method 2: In the Northern Hemisphere, place the watch horizontally, the hour hand points to the sun, and the bisector line between the hour hand and the 12-o'clock scale points to the north-south direction.

Note: To determine the direction by the above method, the exact local time must be used, for example, the local time in Urumqi is Beijing time minus 2 hours and 9 minutes; Also, these methods cannot be used south of the Tropic of Cancer, because the closer you get to the equator, the sunlight is almost direct, and it is difficult to discern the direction with a watch.

Buy a compass and everything settles.
