Weather By The Moon Earth. That does not mean that the Southern Hemisphere has no air, because if that was so everybody would suffocate. It merely means that as there is a bulge in the atmosphere, and so more of it is on the Moon’s side. The Moon gravitationally pulls it because the atmosphere is a movable fluid. Consequently there is always an atmospheric bulge beneath the Moon. Why is there not an atmospheric bulge equally on the opposite side of the Earth? Air acts as a liquid, but only in the sense that it can be moved around due to its fluidity. Bearing in mind that gravitation only has a pulling effect, the result is that the atmosphere is stretched under the moon and becomes more compacted on the opposite side of the earth. The difference between the air and the sea is that gases are by their nature compressable and stretchy, whereas water is neither. With water there is a lag, due to the slowness of water to move against itself. Although some, there is not nearly so much lag with the atmosphere. Earth rotates at 1000mph and jet streams can go 500mph, so the air bulge moves almost as fast as the Moon. At Perigee (when the moon is closest to earth, once per month)the atmospheric bulge of things on Earth towards the Moon is enhanced. After all, the Moon is closer and so exerts more gravitational pull. The stretching then gets more pronounced, as the air tide increases as does like the sea tide, a fact known to fish as they stay out at sea during Perigee and do not venture close to land. These tides in the atmosphere have some effect upon 84

Tides radio reception. Before satellites were employed, long distance radio communication was made practicable by the presence of reflecting layers in the upper part of the atmospheric blanket, known as the ionosphere. Researchers showed that reception was best when the Moon, Earth and Sun are in a straight line(either Full or new Moon) The atmosphere keeps two things at bay - the intense searing heat of the Sun and the murderous cold of space. Wherever the atmosphere starts to thin, either of these two can enter more easily. Through less dense parts of the atmosphere, the cold of space descends and if rain is about, causes greater condensation of water droplets so that the rain falls. Since air behaves nearly as an ideal gas, and vertical distance is proportional to volume over a specified surface area, the thickness between two pressure levels is proportional to the mean temperature of air between those levels. So low values of thickness mean relatively cold air. That’s why the Moon, if over the Northern Hemisphere could bring bad weather news for the Southern Hemisphere. The effect of the lower air tide is opposite for summer and winter. In the hotter season, the relative lowering of the atmosphere offers relatively less resistance to the sun. With less protection from the sun’s fierce heat, heat waves can ensue. In winter the lower atmosphere can bring increased cold which can translate into snowfalls and storms at night when the Sun no longer is in the sky to warm the ground. That is why a low atmospheric tide effect is common at at night around New Moon time, when the Moon is on the opposite side of the Earth . The rule is; when the Moon is in the sky, there is less 85
