Before the technology of weather forecasting was perfected, people always tried to guard against all kinds of bad weather by simple observation, object patterns and folklore for a long time. Once you practice these methods and get familiar with the sky, atmospheric activities and animal behavior, the weather forecast will be quite reliable.

Methods 1: Observe the sky.

1, observe the clouds. By observing the types of clouds in the sky and the direction in which they move, we can identify many kinds of coming weather. Generally speaking, white clouds and high clouds indicate sunny days, while dark clouds mean rain or storm is coming. Cumulonimbus clouds appear in the sky very early and spread continuously throughout the day, which indicates that bad weather is likely to come soon.

Milky cumulus clouds (formed by sinking air) can cause severe or widespread thunderstorms.

Cirrus clouds or "ponytail clouds" hang high in the air like long streamers, which means there will be bad weather within 36 hours.

Cumulus clouds like mackerel scales also indicate that bad weather will come within 36 hours.

Cumulus clouds and ponytail clouds sometimes appear at the same time. Every time there is, it will rain the next day.

Cumulus tower indicates that there may be showers later in the day.

When nimbostratus darkens and condenses in the air, rain is coming.

Clouds in winter nights indicate that the weather will get warmer, because clouds can stop heat radiation, which will lower the temperature on clear nights.

2. Observe whether there are rosy clouds in the sky. Remember the proverb: "Don't work at sunrise, but rest at sunset." Observe any signs of clouds in the sky (not red sun); Most of the time, the sky is not always obviously orange or red, but the specific situation depends on where you live. If you see rosy clouds at sunset (when you look at the west), this is a high-pressure system formed by dry cold air, which makes the dust in the air active, thus making the sky appear red. Because the general cold front movement and airflow weather are usually from west to east, dry cold air is coming towards you.

Clouds in the morning (where the sun rises in the east) mean that dry air has passed over you, and the low-pressure system that follows (moving towards you) carries water vapor.

3. See if there is a rainbow in the west. This is formed by the rising sun rays reflecting the water vapor in the west. Most storm fronts in the northern hemisphere move from west to east, and the rainbow in the west represents water vapor, which indicates that rain is coming. On the other hand, the rainbow that appears in the east at night indicates that the rain has stopped, and you can expect the next fine weather. Remember: "If it rains towards the rainbow, you should be on your guard."

4. Stare at the moon. If it is red or pale, it means that there is dust covering it in the air. But if the moon is bright and dazzling, it may be because low pressure air makes dust settle, and low pressure means rain. Lunar halo (formed when light shines on the cirrostratus associated with warm front and water vapor) indicates that it may rain in the next three days.

Remember this proverb: "The moon grows hair and it rains in the Ming Dynasty."

Method 2: Feel the wind and air.

1, detect the wind direction. If you can't detect the wind direction immediately, throw a piece of grass into the air and observe where it falls. If the wind blows from the east, it indicates that the storm front is coming; The west wind indicates a sunny day. Strong winds indicate a high pressure difference, which can be regarded as a sign that a storm front is coming.

2. Make a bonfire. The smoke should float smoothly. The spiraling smoke is caused by low pressure, which indicates that it is going to rain.

3. Observe the dew on the grass at dawn. If the grass is dry, it indicates clouds and strong winds, indicating that rain is coming. If there is dew, it may not rain that day. However, if it rains at night, this method is no longer credible.

4. Observe the leaves. Deciduous trees usually expose the bottom of their leaves in unusual winds, which may be because their leaves can only face upwards in normal winds.

5. Take a deep breath. Close your eyes and smell the air. Plants will release some wastes in the low-pressure atmosphere, producing a smell similar to compost, which indicates that it will rain soon. Due to the low pressure, the swamp will release gas before the storm, giving off an unpleasant smell.

There is a proverb: "bees are busy picking flowers, but it will rain in the short term." The smell is getting stronger and stronger in the humid air on rainy days.

6. Check for moisture. Many people can feel moisture, especially their hair (which curls). You can also observe oak trees or maple leaves. Before heavy rain, the humidity is often high, and these leaves curl easily. When the humidity is high, the scales of pine cones meet and open in dry air.

Under wet conditions, wood will give off a smell (pay attention to those sticky wooden doors) and salt lumps will appear.

Method 3: Observe the behavior of animals.

1, watch out for birds. If they fly high, the weather will be fine. The pressure drop caused by the coming storm will make birds' ears uncomfortable, so they will fly lower to alleviate this discomfort. A large number of birds perched on telephone poles, indicating that the air pressure dropped rapidly. Seagulls will stop flying and take refuge on the beach before the storm comes.

Birds will become quiet immediately before it rains.

2. Pay attention to cows. They usually lie down before a thunderstorm. They may also stay together before the bad weather comes.

3. Observe the ant nest. Before it rains, some ants will nest in very steep places.

4. Observe the turtles nearby. It is said that they often look for higher places before heavy rain. You may see them on the road 0 to 2 days before it rains.

Method 4: Create your own forecasting method.

1, learn the key forecasting principles. Any forecasting method is based on the same principle: low pressure and rainfall, and the main weather system moves from west to east. The key to forecasting the weather is to know the precursors of local pressure changes. Although the weather system usually moves from west to east, there may be some storms that are not like this, and the situation in each place may be different.

2. Observe with your heart. You can think about the law of weather change and test your hypothesis. You can read various guide articles to improve your ability to predict the weather. Residents who are expected to be outdoors, especially farmers and commercial fishermen. , you will learn to observe various trends to obtain information and understand the long-term weather patterns and seasonal changes in its local special geographical location.

Pay attention to the special local animals and plants. Starting to observe these patterns will give you a better understanding of the weather patterns.

It is suggested that you can use barometer (or homemade barometer) to check the change of barometric indicator. Write it down in your notebook and pay attention to what happens when the air pressure changes. Be careful, maybe you can come up with a unique local weather forecast method.

The information about the direction provided in this paper (that is, the west wind indicates sunny days) is mostly applicable to the northern hemisphere. Check the general weather trends in your area.

Regarding the types of these clouds, the old sailors have a proverb: "ponytails and mackerel, tall ships can only carry short sails." Another sentence is: "Mackerel and ponytail, the crew need to close the sails."

Early warning of some bad weather, such as tornadoes, is difficult to predict accurately. Make sure it is consistent with your local weather forecast and know how to ensure safety before the storm warning.

It is not very scientific to predict the weather like this. Don't risk yourself or others' lives because of these experiments.
