Weather changes are due to differences in temperature, moisture content and pressure between the atmospheric air masses that circle the planet. Generally speaking, weather is determined by the current state of the atmosphere in a particular area, and is also affected by seasonal changes due to the Earth's rotation around the Sun.Know More
Atmospheric pressure is the most important factor in weather change, as high pressure causes the air to slowly flow downwards and spread out, whereas low pressure causes the air to rise, where water vapor then condenses into clouds. High pressure weather systems tend to result in mostly clear, cloudless days, as the sinking air prevents clouds from forming. On the other hand, the air cools down as it rises in low pressure systems, causing the water vapor to turn into clouds and eventually be released in the form of precipitation.
The Earth's atmosphere is formed of these different air masses, which are constantly moving at different speeds. In the northern hemisphere, the air masses move in a clockwise direction, whereas the air in the southern hemisphere moves in the opposite, counterclockwise, direction. The moving and/or collision of these air masses leads to wind and storms, which result in changing weather patterns.Learn more in Weather Seasons
The weather during the season of spring varies depending on location, but it is usually marked by an increase in temperature and rain. In areas that receive snow during winter, the snow begins to melt. This can lead to flooding of waterways.Full Answer >
The elements that make up weather are temperature, humidity, precipitation, visibility, wind and atmospheric pressure. Weather describes the behavior of the atmosphere and what effect it is expected to have on the population.Full Answer >
The differences between spring and autumn include temperature, time of year and length of day. Spring is the season that happens after winter, while autumn is the season that happens after summer. The physical appearance of spring and autumn are different as well, as trees bloom in spring and turn in autumn.Full Answer >
Sound does not actually increase in amplitude, or loudness, in the cold. However, two factors come together and make people perceive sound as much louder in the cold: the cold itself and the snow that often comes with it.Full Answer >
