The amount of sunlight striking an area, the geographic location of an area, the air pressure surrounding an area and the amount of water in the atmosphere all influence the local weather. Each of these components interacts with the other components, and they may exacerbate or moderate each other.Know More
The amount of sunlight striking an air mass influences its temperature. As the air heats up, it rises in the air column and begins sucking cool air in behind it. This causes the winds that drive much of the planet’s weather systems.
The weather is also affected by the local geography. For example, mountains often block winds and rainfall. This causes one side of the mountain to have very high amounts of rainfall and lush vegetation, while the far side of the mountains remain very dry and desolate.
The air pressure in an area can impede or encourage the flow of weather systems. In general, air masses flow from areas of high pressure towards areas of low pressure. Usually, storms occur in areas of extremely low pressure.
The amount of water in the atmosphere affects the local humidity and rainfall. Air masses that move across bodies of water often draw water up into the air before depositing it somewhere else as rain, snow or sleet.Learn more about Weather Forecasts
Weather and climate are both terms used to describe temperature, atmospheric conditions and precipitation. The only difference between weather and climate is a measure of time. Weather reflects short-term changes within the atmosphere, while climate is determined by averaging daily and seasonal weather over a long period of time.Full Answer >
Climate affects the temperature, amount of water and amount of sunlight in an area. These factors affect the look of the land, as well as what types of plants and animals can survive in the biome. When the climate changes drastically, it can have seriously negative impacts on the biome.Full Answer >
The first signs of an approaching warm front include a general movement of air from southwest to northeast, a drop in air pressure, and warmer air found behind the movement of the front. Warm fronts tend to signal a general change in weather.Full Answer >
To understand a barometer's readings, it is necessary either to understand the relationship between air pressure, sea level and weather or to know what certain barometric pressure readings correspond to in terms of anticipated weather. Using the second method, one will only know what weather to anticipate; with the first one, someone is likely to understand the reason for the weather prediction.Full Answer >
