But thunderstorms are not the only way the atmosphere conducts electricity – the solar wind and ionospheric wind play a role too. In contrast, locations along the equator have winds that primarily come from the east. These are called the “trade winds” or “tropical easterlies” and begin at around 30 degrees latitude in both the north and south. In fair weather when air pressure is high, earthly smells tend to get stored in their source. When low air pressure arrives before rain, the scents are released and odours can be smelt. In our climate, heavy rain is unlikely to last for long periods of time.

If ash trees bud before oak trees, expect a drier summer; if the reverse, expect a wetter summer. When a storm builds rapidly, it’s often stronger and faster than when a storm builds gradually. A strong thunderstorm has an average speed of about 30 miles per hour, meaning it will generally only last a few hours. A gentle rain shower, though, can travel at a fraction of that speed, and can last for a few days. In some cases, if the air has some turbulence, the fog can thicken and even produce rain. This isn’t rain from a low pressure system, though, meaning the vapor will soon be spent, and the rain will not last long.

In summer, an easterly wind will mean it is cool on the east coast but warm elsewhere, usually with clear skies. All occlusions will cause a rise in pressure, a change in wind direction and precipitation will slowly clear when they have passed. A weather system with gradual changes is more likely to stick around for a while than a weather system that moves and changes quickly. If pressure and temperature changes happen slowly, however, it’s very likely that the weather system will stick around longer.

In the section, “How Does A Stationary Front Form?”, you can get a good idea of how a stationary front looks in context and how it may be depicted during a weather forecast. The farmer wondered whether the adverse weather had affected his wether. olivia culpo nose job Weathering, derived from weather, is the result of exposure to wind and weather. Any opinions, findings and conclusions or recommendations expressed in this material do not necessarily reflect the views of the National Science Foundation.

However, gray skies mean that the storm is affecting a large area and may remain for awhile. If you live in an area that always has high humidity, rely on other observations to predict the weather. When smoke spirals downwards, it means that bad weather is very close. The low-pressure system is already in place over your area. Generally, most of us rely on forecasts to tell us what kind of weather to expect.
