What is Coriolis Effect?

Coriolis Effect

đŸ‘‡


The Coriolis effect is the apparent curvature of global winds, ocean currents, and everything else that moves freely across the Earth’s surface. The curvature is due to the rotation of the Earth on its axis. The effect was discovered by the nineteenth century French engineer Gaspard C. Coriolis. He used mathematical formulas to explain that the path of any object set in motion above a rotating surface will curve in relation to objects on that surface.

 If not for the Earth’s rotation, global winds would blow in straight north-south lines. What actually happens is that global winds blow diagonally. The Coriolis effect influences wind direction around the world in this way: in the Northern Hemisphere it curves winds to the right; in the Southern Hemisphere it curves them left. The exception is with low pressure systems. In these systems there is a balance between the Coriolis effect and the pressure gradient force and the winds flow in reverse.

 Satellites appear to follow curved paths when plotted on world maps because the Earth is a sphere and the shortest distance between two points on a sphere is not a straight line. Two-dimensional maps distort a three-dimensional surface in some way. The distortion increases with closer to the poles. In the northern hemisphere a satellite’s orbit using the shortest possible route will appear to follow a path north of the straight line from beginning to end, and then curve back toward the equator. This occurs because the latitudes, which are projected as straight horizontal lines on most world maps, are in fact circles on the surface of a sphere, which get smaller as they get closer to the pole. This happens simply because the Earth is a sphere and would be true if the Earth didn’t rotate.

 The Coriolis effect is of course also present, but its effect on the plotted path is much smaller, but increases in importance when calculating a trajectory or end destination. The effect becomes very important when you need to plot trajectories for missiles or artillery fire.

Earth's shine seems to be fading due to global warming as the oceans heat up

  In recent years, the climate change crisis has escalated to unprecedented levels, resulting in unimaginable and life-changing consequences. An acclaimed new study contends that global warming is dimming our planet, literally! Global warming is causing the Earth's brightness to decrease, according to a new study. Now you're probably wondering, "how do you even measure something like that?" But researchers have their ways. Keeping track of the Earth's shine requires them to calculate the Earth's 'albedo', or reflectance. The albedo is calculated utilizing something called the 'earthshine'. The crescent moon is most noticeable immediately after sunset or before sunrise, when its dazzling crescent gives way to a dark disc with a faint glow. A crescent moon's unlit parts are known as earthshine because they are glowing from the light reflected from the Earth. The study revealed that earthshine data over the last three years indicates that our ...

What is Gun Cotton? How is it different from Black Gun Powder?

  Nitrocellulose (also known as cellulose nitrate, flash paper, flash cotton, guncotton, pyroxylin, and flash string, depending on form) is a highly flammable compound formed by nitrating cellulose through exposure to a mixture of nitric acid and sulfuric acid. One of its first major uses was as guncotton, a replacement for gunpowder as a propellant in firearms. Guncotton was actually developed as a “Smokeless Gun Powder”, Essentially, the main difference between Black Gun Powder and Smokeless Gun Powder is that you need almost zero incombustible components. The key problem with black powder was that it produced a cloud of smoke, not only from Un combusted carbon but also, unavoidably, from ash, the salts formed from whatever anion happened to latch on to the sodium or potassium cations present from the nitrates in black powders. Black powder ash contains a high proportion of potassium or sodium sulfates and carbonates, and because the inorganic saltpeter component was about 2/3 of...
