Indications of foul weather include a change in wind direction and speed due to low- or high-pressure systems, an increase in ocean swells, thunder, lightning, the formation of low or dark clouds and red or pink hues in the sky at sunrise or sunset. These are the traditional methods for detecting an approaching storm.Know More
Stratocumulus clouds are clumpy layers of clouds closer to the surface that indicate a storm is on the horizon. Thicker nimbostratus clouds that appear in layers but block the sunlight have the potential to emit precipitation. Towering cumulus clouds indicate the most dangerous weather. These form vertically and produce precipitation along with thunder and lightning. If the conditions are right, these clouds create updrafts that lead to tornadoes. Wall and shelf clouds are the beginning of an approaching storm that has the potential to produce tornadoes as well. Signs of a tornado include hail, rotating clouds and a sky with a green hue.
Thunderstorms produce wind upwards of 60 miles per hour. Hail often accompanies thunderstorms, especially those with the potential to produce a tornado.
Before the invention of modern weather instruments, such as weather satellites and buoy reports, weather observers had to look to the swells of the ocean, the color of the sky and lights around celestial bodies to predict weather.Learn more about Weather Forecasts
France has a climate similar to that of the northwest coast of the United States, with moderate temperatures and around 20 to 40 inches of rainfall a year. There are climate variations between the different regions of France.Full Answer >
The tilt in the planet's axis is the main factor that causes weather to change, according to NASA. Earth's distance from the sun, its orbit and the atmosphere all contribute to weather shifts.Full Answer >
Weather forms primarily from conditions in the local atmosphere that change frequently over short periods of time. Weather, in the broadest sense, is the condition of the atmosphere in a set location that varies on a daily, weekly, or monthly basis. Weather is created by several different factors, such as temperature of the surrounding land and air, levels of humidity and type and volume of precipitation.Full Answer >
The main difference between weather and climate is the measure of time. Weather refers to the short-term atmospheric conditions in an area, while climate represents the average daily weather over a relatively long period of time. Climate also includes statistics of weather extremes.Full Answer >
