That the weather changes east from the west occurs in the limited areas, such as Japan, Europe, the United States. This is because a strong wind blows from the west to the east by the westerlies which are over near Japan. Since the front and atmospheric pressure which occurred under this influence in Korea etc. are east passed from the west in many cases, the weather is also put together to it and changes east from the west.In the area near the equator, such as the Philippines and Guam, since a strong wind called the trade winds blows to the east, the weather changes from the east to the west.

Since autumn, winter, and humidity fall, the body burns energy in order to maintain body temperature.The amount of blood is restricted and nutrition will stop therefore, spreading in the surface of the skin, or the terminal part of hand and foot so that excessive energy may not be consumed. since the amount of secretion of the sebum which carries out the barrier of the skin becomes the minimum, the time evaporates [ moisture of the skin ] more often.As a result, it becomes easy to dry skin.
