1. Guess the riddle:
Though armless, but it happens
The pines are uprooted,
So sometimes he gets angry.
Just that he was everywhere -
A moment - and it is nowhere. (wind)
Guessed? It's…the wind.
At the lesson of the surrounding world, our teacher told us about natural phenomena. It turned out that nature is filled with many different phenomena, interesting, beautiful and even frightening. We want to dedicate our work to such a phenomenon as the wind.
It is impossible to see the wind, but it is impossible not to notice how it sways the crowns of trees, drives clouds into the distance, circles snowflakes.
There are songs and poems about the wind. Many turn to the wind for help literary heroes. There are many folk signs associated with the wind.
We liked these:
● A warm wind in March promises an equally warm but rainy summer.
● The wind that blows on Palm Sunday will prevail throughout the summer.
I became interested:what is "wind"? Where does it come from and why does it blow? What is the importance of the wind to humans? Is it possible to predict the direction of the wind from folk signs?
These are the questions we will find answers to in our work.
Experience #1
What is the wind?
To understand what the wind is, we took the turntables and went outside: I noticed that the turntables did not move at first. And as soon as the wind blew, they began to spin, quietly at first, and then stronger and stronger.
Conclusion: Wind is the movement of air.
Experience No. 2
We can check this conclusion in other experiments by trying to create a wind with our own hands:
With the help of a fan:
I took the fan and waved it at me. I felt cool, breeze. I made the air move.
With a balloon:
I blew up a balloon, but didn't tie it. The air began to come out again, and I again felt the breeze.
But the air can be both warm and cold.
To test this, we conducted the following experiment.
Experience number 3 cold and warm air.
When I sat down on the floor, I felt cold. And when I climbed onto the second floor of the bed, I felt warm.
Conclusion: The wind is first formed from two layers of air, and only then it starts to blow..
It turns out that cold and warm air move differently. We also verified this experimentally.
Experience No. 4 movement of cold and warm air.
I opened the balcony door and lowered the lighted candle on the threshold. The flame of the candle began to deviate towards the door. Then I moved the candle up - the flame of the candle began to deviate towards the room.
Conclusion: Warm air rises, it is light. A heavy cold air rushes down to the warm place.
Air moves continuously, it constantly rises and falls, and also moves horizontally.
It is the horizontal movements of air that we we call it wind.
Each wind has its own name.
The name of the wind gets on the side of the horizon, from where it blows.
the north wind blows from the north
the south wind blows from the south
the west wind blows from the west
the east wind blows from the east
southwest wind blowing from the southwest
northwest wind blows from the northwest
southeast wind blows from the southeast
northeast wind blows from the northeast
Determine from which side the wind is blowing and with what force we can use a special device - a weather vane.
Slow air movement it's a breeze. I watched a light breeze when I was relaxing with my parents at sea.
Strong wind is the rapid movement of air. Such winds are called hurricanes or typhoons. And under thunderclouds tornadoes or tornadoes may occur. Such winds can cause enormous damage: they destroy houses, overturn cars, knock down power line masts. Sometimes it does not do without human victims.
How does the wind help a person
But the power of the wind has long been used by man.
In travels and discoveries (navigation, balloons);
As a source of clean energy;
Wind is an important factor in climate formation, formation and movement of clouds, erosion of the planet's surface; an assistant in the transfer of plant seeds and the fertilization of plants by pollen.
Conclusion: So the wind can be not only an enemy, but also a friend of a person.
Is it possible to determine the direction of the wind by folk signs?
What are omens
The very word "sign" was formed from the words - note, notice. The first signs began to appear in ancient times, at a time when people first began to closely observe the world around them, the behavior of animals, weather changes, and the like. Even such trifles as the color and shape of the clouds gave people something to think about.
A sign is a phenomenon, an event that is popularly considered a harbinger of something.
According to the duration of action, signs are long-term and short-term.
You can determine the weather not only by local signs: clouds, precipitation, the moon, stars. But also for living beings: animals and plants.
We were interested in the signs associated with the wind. Since in Chelyabinsk, according to the city weather station, 76% of the days of the year are windy. The average wind speed is 2-5 m/s. strong winds with a speed of 15 m/s and more are observed annually, more often in the month of May, on average, 14-16 days with a strong wind are noted a year.
Chapter 2
To find out whether it is possible to predict the direction of the wind according to folk signs, we organized a weather observation.
We liked these signs associated with the wind:
● "A warm breeze in March promises an equally warm but rainy summer"
● "The wind that blows on Palm Sunday will prevail throughout the summer"
To test your hypothesis: “Is it true that a warm wind in March promises the same warm but rainy summer”
I kept a weather diary, where I noted the direction of the wind throughout March 2016, as well as precipitation and air temperature in the summer months.
To find out if the wind was warm in March, and these are southerly winds, I made a wind rose for a given period of time.
In March dominated warm winds south direction.
The air temperature throughout the summer months was quite high: it did not fall below 18 degrees, and the highest - the air temperature was in August - 34 degrees.
For the entire summer period there were 34 days of rainy and cloudy weather.
Thus, a popular sign: "A warm wind in March promises the same warm, but also rainy summer." partially confirmed.
To test my hypothesis: “Is it possible to predict the direction of the wind for the whole summer in the direction of the wind on Palm Sunday?” I also kept an observation diary in which I noted the direction of the wind in the summer and noted the direction of the wind on Palm Sunday.
I got these results:
If you believe the sign, then the prevailing wind in the summer months should also be northwesterly.
Having built a wind rose for the summer months of June, July and August, I got the following results:
In my experience
in June, the north and northwest wind prevailed
in July, the north and northwest wind prevailed
in August prevailed - south and southwest wind
Thus, the popular sign "The wind that blows on Palm Sunday will prevail throughout the summer" was partially confirmed.
CONCLUSION: Summarizing the data obtained, I came to the conclusion that in most cases it is not always possible to predict the direction of the wind according to folk signs.
During its research work I learned a lot about such a natural phenomenon as the wind. I learned about the causes of its occurrence, about the impact on human life and the world around. And found out that it is not always possible to predict the direction of the wind according to folk signs.
Thank you for your attention!
Can we predict the direction of a breakout?
Following the traditional tactics of buying at the bottom and selling at the top of the configuration, we will, by definition, not be successful when the final break occurs. Since the loss cannot be capped by placing a stop loss just at the boundaries of the configuration (where it is inevitably activated on a false breakout), in our search for alternatives, we found only one option: to take positions in the expected direction of the breakout. How do we know which direction the breakthrough will take? Look for signs of a fundamental imbalance between buyers and sellers. Often they can be detected using the following indicators˸
1. General trend. The most important signal is the previous trend. He submits strong signs future movement, as up to now most of the consolidation zones have proven to be periodic fights between traders in an ongoing trend. Only statistics says that the breakout is in line with the trend.
2. Configuration. We know that most configurations give a signal about the development of a trend. Quite often it has good indicative properties.
3. Volume. Remember that "volume follows the trend". If we know the trading volume on the ups and downs within the configuration, then we can determine the direction of the breakout.
4. Gaps. If price gaps occur during a fall, for example, within one day, this is a sign of weakness in buyers, just as price gaps on an increase naturally
312 Psychology of finance
a sign of seller weakness. Gaps, or simply sudden shifts in direction, typically reflect a breakout in the direction of the gap.
5. Test breaks. There are two types of trial breakouts: premature and false. A false breakout is so called because it is immediately followed by a (true) breakout in the opposite direction. "Immediately" means "within a few days or even hours." If this does not occur after a failed test break, then the move is premature; the final break usually occurs in the same direction as the premature move.
6. Generality. As mentioned, signals from related markets often tell us a lot about what a particular market (such as a given stock) will do.
If we set the direction of the breakout, this will make trading in price congestion zones a fairly safe pastime.
