Why Wind Blows

A long time ago the Greeks thought wind was the breath of gods. They were happy with this explanation until the philosopher Anaximander realized there was a scientific explanation. I'm sure your teacher would agree with him. Here are a few facts you need to know about wind.

Breathe of Fresh Air

Without wind, we wouldn't have any change in the weather. That means no snowmen, no tans and no singing in the rain. Wind is air moving horizontally. It's the result of air movement over the Earth. Air moves because of pressure systems - it travels from areas of high pressure to areas of low pressure. The two reasons these pressures change around the earth are:
1. Earth Moves: As Earth moves, it drags the atmosphere around with it, which causes the air to mix with the higher level atmosphere. This creates turbulence and pressure systems.
2. The Sun's Heat: The air around Earth changes temperature all over, depending on the time of day. As the air warms up, it rises. In polar regions where the sunlight spreads over a greater area, the result is less warm air. This means the air over the poles is denser than the air over the equator.

As air rises, low pressure areas are created below. Air in high pressure areas then rushes to fill in the gap. If there's a big difference between the pressure, the flow of air between the two points will be stronger.

Measurements

Wind speed is measured by an instrument called an anemometer. It has three cups that catch the wind and causes the instrument to rotate. To make the wind speed official, the anemometer has to be 30 feet above ground. Downtown areas can be just as windy as the tops of mountains. Tall buildings on either side of the street can channel the wind, forcing it to blow much faster. The world record for the highest wind speed is 231 miles per hour. This was at the summit of Mt. Washington in New Hampshire.

Name that Wind

Some reoccurring winds have been named by meteorologists (scientists who study weather.) Here are a few wind names and a brief description of that wind.
Blue Norther: An arctic cold front moving into Texas.
Knik: A fast moving wind from the southeast to Palmer, Alaska.
Northeaster (also called Nor'easter): A strong wind linked with major storms and winter weather along the mid-Atlantic and New England areas. Squall:Most of the time, it's a sudden and violent wind caused by many continuous thunderstorms - usually over water. It can be over 100 miles long and bring rain and hail.
Chinook Wind: A warm dry wind that blows from the sea in some regions of the Pacific Northwest that causes a rapid rise in temperature.
Trade Wind: A wind blowing constantly in one direction. These winds mostly happen in the tropics.
Gale Warning: When winds reach between 32 and 53 miles per hour, the National Weather Services gives this warning.
Storm/Hurricane Warning: When winds reach between 54 and 74 miles per hour the National Weather Services also issue this warning.

(Requested by @snoopynwoodstock123 ) (Sorry this one's shorter than usual. I wanted it to be to the point, but it was fun to write. Enjoy!) Shin and Oka were bent over an array of smoking potions, dark vials, and musty powders, arranging them in the intricate patterns of ritual. Silent except for panicked, labored breathing, Oka grabbed a vial of a sickeningly sweet, dark red liquid and began tracing the lines of charcoal pencil already drawn onto the stone floor. Oka closed her eyes for a second, holding her breath. “Shin, hand me the book.”  He did so with trembling hands, and Oka turned to the proper page of the dusty book. The pages almost crumbled in her hands because of age and wear. The exotic and disgusting ingredients, the pentagram drawn upon the floor, and the pages and pages of Latin text proved that this was not your every-day ritual, but instead the last ditch effort of defeated prey to escape from a hunter that prowled throughout the hallways, prodded on by insane lust. For the past six hours, a first year student had been rampaging throughout the school, slaughtering all in her path, and, after being contacted by the police, she took hostages of all surviving the initial attack. Oka and Shin had just managed to escape and begin to prepare an attack of the supernatural kind. Oka took a deep breath and began reading the accursed text. Shin held his breath as the words on the water-damaged page began to glow a faint red, glowing brighter and brighter and pulsating like a heartbeat as the seconds ticked by, each feeling like an eternity. Suddenly, they heard a sound that sent chills like spiders of ice racing down their backs: a giggle, a laugh from just beyond the door and footsteps prowling the surrounding halls. There was a monster lurking outside with an intent to kill. Oka’s voice lowered to a barest whisper, but she could not stop the chant, or they would have to begin the process over again, and that would take time they didn’t have. The footsteps grew closer, each foot fall sounding like a sledgehammer in the silence of the corpse-ridden school, echoing in the ears of the two hidden students. Shin began to tremble, and Oka wanted comfort him so badly, but she could not put down the candle of dripping black wax in her hand or murmur any words except for the ancient Latin text. Then, with a glint in his eye of fierce determination, Shin stood up, and Oka’s eyes followed him curiously while her mouth continued to usher forth the chant. What was he-? “Oka,” he whispered. “She- no, it is going to find us before the ritual is complete.” Oka’s eyes suddenly widened in panic as she began to predict in her mind what he would say next. Shin continued, “I won’t be of much help in the fight, but I can be a distraction.” Shin held up is hands to try and calm Oka as she began to shake her head furiously, but unable to say any words to stop him. “It’ll buy enough time for you to achieve power enough to stop her. Goodbye, my friend.” Shin bent down and gently kissed Oka on the forehead. Oka screamed internally, begging him not to go, but he could not hear her thoughts. With the fate of a martyr before him, Shin reached up to the door that was framed by streams of light, and at the last second, he turned back to Oka and smiled sadly. He blinked, and a single tear rolled down his face. Then his head turned back to his fate. He reached up, and pushed the door open. The last seconds he was in view felt like slow motion as Shin stepped away from the dark room into the harsh, unyielding light that enveloped him like a gateway to wherever Shin was going after death. Then, the door swung shut. Oka could only watch the doors close and hear the echoing screams of laughter and the disgusting sounds of a knife penetrating human flesh. Screams were swiftly silenced but ended with bubbling croaks. Oh, Shin, she thought in agony to herself as tears streamed down her face. Shin, why did you have to do that? Curse this ritual that prevented me from saving him, from stopping him! It’s all my fault, oh, Shin!! A final, gasping gurgle issued from the space outside, signaling Shin’s death.  Oka said the ending words of the ritual with gasping, sobbing breaths. A dark mist began to swirl, like living shadows, and Oka could feel the rush of strength and passion that was poured into her form as arms, pale as ghosts with fingernails red as blood, erupted from the ground like hellish flowers in a circle around the now-floating Oka. They responded to her thought and will, twitching with anticipation of vengeance. Oka could feel the strength and speed coursing through these new extensions to her form. With a mere flick of her finger, the arms reached up and tore the door separating Oka from her enemy effortlessly, leaving the doorway dusty and open. Yandere-chan, the monster, a psychopath for love, stepped through the door way, covered with the blood of one of Oka’s only friends. She looked at Oka while stroking her dripping blade with the look of someone exhilarated by the thought of a true fight at last, and Oka screamed with tormented laughter somehow more nightmarish than Yandere-chan’s own. This was going to be a hell of a fight.
