It was sunny and sunny just now, and in less than half an hour, the lead-colored clouds pushed from the southeast, thick as a winter quilt.

[This weather is so scary, is it going to snow? 】

[It seems to be, I remember that the professor said yesterday that it will snow the day after tomorrow, but this is only the next day? 】

[There are errors in the weather forecast, right? 】

[Fang Shen run quickly, otherwise it's too late! 】

The friends of the water were anxious at the sight of the clouds, and they could still remember the power of the last blizzard. If this is trapped, the geese and birds may be frozen to death, not to mention whether the glider can fly.

Etienne pulled Bi Fang's robe nervously.

"Boss, it's going to snow."

Bi Fang naturally saw the clouds drifting over slowly, but he was not in a hurry, and it was useless to be anxious.

"Don't worry, it's useless if you're anxious. There will be some time before the clouds float over. The most important thing for us is to find the current position, determine the right direction and fly again, otherwise the route may become more and more severe, in case we run into humans. Going to the city, the wild geese will remember that it is very dangerous."

"You can go and put out the fire first, first pick a few pieces of charcoal, wrap it with soil, and take it away, and then pour it with water. Remember to cover the soil."

Hearing what Bi Fang said, Etienne could only bear it temporarily. According to Bi Fang's actions, his trembling feet still exposed his tension.

Bi Fang explained to the audience at the same time as he was calculating, and he didn't seem to panic at all, but a discerning person could still tell that he was recalculating a value.

This value was calculated incorrectly just now.

"The number of sun elevation angles = arctan (stick height and shadow length), and then the latitude of the observation point = 90-the number of sun elevation angles + the declination of the sun obtained by looking up the ephemeris, and the latitude is calculated in this way."

"If the days are clear in the future, repeat the observation and calculation several times to average, which can improve the accuracy. If this method is properly calculated, the measurement accuracy error will be less than 13,000, and the positioning accuracy can be no more than 4 kilometers."

Bi Fang's hand speeded up significantly, his speech became tighter and tighter, and the numbers were even more connected with each other.

"There are two most accurate days in a year for measuring the position with the sun: the vernal equinox and the autumnal equinox. Because these two days have the same length of day and night in the world, the true solar time and the peace solar time are the same. In addition, it is necessary to understand the meridian of the east eighth district, which is 120 east longitude. °."

"This longitude happens to pass through Hangzhou instead of the capital. The so-called capital time is actually the actual local time in Hangzhou. The time difference when calculating the longitude is to be summed up in the geographical distance from Hangzhou."

Etienne looked more and more anxious, as if he was about to jump his feet, urging him constantly, and even went to untie the body of the glider tied to the tree.

"Ok?"

"Soon."

"Ok?"

"It's fast, fast, fast! Go get your clothes!"

Bi Fang frowned, and he knew better than anyone else that the clouds seemed to move slowly, but in fact they were running at a speed of more than 40 or even more than 50 kilometers per hour, almost as fast as a car!

It only takes less than ten minutes to catch up with them!

"Okay?" Etienne hugged his jacket tightly, jumping anxiously as he watched the clouds that were about to fall above his head.

This time Bi Fang didn't speak, he opened the manuscript paper, traversed with a pencil, and a coordinate suddenly appeared on the paper.

(69°1\' north latitude, 24°76\' east longitude)!

[Fuck, awesome! Really figure it out! 】

[Too awesome! 】

[Spaceship and knees sent! 】

[Big guy doing math problems at the moment of life and death! Who else! 】

【what? A blizzard is coming? Please let me finish this question first]

"Go, get on the plane!"

Etienne nodded excitedly, quickly recalled the geese and jumped on the glider. Bi Fang followed behind and drew out the map, found their current location based on the latitude and longitude, and it was really wrong!

The route that was originally in the southwest direction has been changed to the southeast direction!

Bi Fang put on some damp clothes, put away the map and went to the lake. He was taken aback when he saw Etienne sitting in the driving seat and waved him to sit back: "What are you doing? Sit back!"

[Hahaha, which boy doesn’t have the heart to drive a glider]

[Fang Shen is scared]

[This is a habit]

Etienne also realized that he was in the wrong position, smiled and crawled into the back row.

Bi Fang sat in the driving position, pulled the engine, and the spiral blades quickly rotated, driving the glider to slide slowly.

Etienne kept whistling in the back row, and some panicked geese gradually gathered and arranged the adult glyphs quickly. With one experience, the organization was very fast this time.

Pieces of snowflakes began to fly, falling on the lake for a long time, Etienne reached out to take it, and found that the snowflakes were surprisingly large, almost the size of a bean.

"This snow falls too late, and a large amount of water vapor accumulates together, which may cause severe sudden snowfall." Bi Fang looked serious and wished that the propeller turned faster.

It was just far away, and everyone didn't feel anything. Now the cloud was approaching, only to realize that the cloud was terribly thick, and the sun was almost completely obscured, and no sunlight was visible.

The terrifying and terrifying wind resounded across the sky, disappearing into the boundless blizzard, just like unleashed fierce souls.

“If I’m not mistaken, this is a rain layer cloud, which is often evenly covered throughout the sky. The thickness is generally 4 to 5 kilometers. And the light of the moon is covered!"

The water friends who had no idea about data were panicked.

Finally, when the snow was getting bigger and the clouds almost covered the top of the head, the glider finally left the water.

The water friends began to cheer. As a result, as soon as the glider took off, a violent wind suddenly lifted the plane, almost facing upwards at 70 degrees, scaring the audience to a horror. Fortunately, Bi Fang pulled the joystick in advance and lowered the nose. Only barely controlled the plane, and took advantage of the wind to climb!

Facing the gusty wind, the glider flew extremely fast, and Etienne, who was sitting behind, felt like he was riding a roller coaster, with a strong sense of sticking to his back, and it didn't take long for him to start flying away from the clouds.

The plane gradually calmed down, and Etienne looked behind him, and found that none of the eighteen wild geese were missing, and he was relieved that they were all safe and sound.

He just flew so fast, he was worried that the wild goose would fall behind.

Bi Fang looked back and saw Etienne's nervousness, and explained: "Don't worry, the flying goose is very fast, it can fly 68 to 90 kilometers per hour, even if it is a long journey of more than 5,000 kilometers, it only takes more than a month. , Faster than the wind speed in a blizzard, and the wind direction is downwind, we fly fast, they will not be slow."

[It was too dangerous just now~www.readwn.com~ Fortunately, it flies early, otherwise it will be gone.]

[Yes, if the blizzard suddenly comes, isn’t it all over? Fortunately, the plane flies fast]

[Speaking of the last time Lao Fang Mohe did not measure the latitude and longitude? Wouldn't it be possible to spot rescue after testing? 】

[You are stupid, the essence of measuring longitude and latitude is actually to look at the height of the celestial body. The snowstorm in Mohe for a few days, there was no sunshine, do you look at the celestial body in Nima? I have spoken my mind. 】

[Awesome, there is a grumpy man who understands it! too strong】

Bi Fang watched the friends blowing the water and smiled. This time he was indeed lucky and escaped before the blizzard. But what made him a little worried was whether the climate change in Finland would affect the North Sea. airflow?

A storm at sea is much more dangerous than a snowstorm on the road.
