Please let snow white sushi roll know if you agree. Ad-free Use meteoblue weather forecasts without advertising and tracking. The rainSPOT shows the precipitation around you. Your current location is in the center.
In this example, there is light rain about 10 km northeast and heavy rain 5 km southwest of you. SPOT is a simplified weather radar map that works for a 7-day forecast as well. It also indicates spatial uncertainty: If the entire rainSPOT area is solid blue, it is more likely to rain at your location than if there is only a few blue boxes. The predictability indicates whether you can rely on the current weather forecast.
With high predictability, the weather will very likely be as forecast. With low predictability, the weather forecast is uncertain and could easily be wrong. Keep an eye on updates in this case. Predictability is computed by comparing hundreds of forecasts made by national weather services and institutions around the world. There are many ways to put our weather and climate data to practical use, and many ways to display them – by app, web, email, and API. This is the latest display form: a Blanket.
Is warming a cause for the blanket or the blanket a cause for warming? This is just an example for Basel, Switzerland. On this Wikipedia the language links are at the top of the page across from the article title. The physical properties of snow vary considerably from event to event, sample to sample, and over time. Snow comprises individual ice crystals that grow while suspended in the atmosphere—usually within clouds—and then fall, accumulating on the ground where they undergo further changes. Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air. Snowflakes nucleate around particles in the atmosphere by attracting supercooled water droplets, which freeze in hexagonal-shaped crystals.
Major snow-prone areas include the polar regions, the northernmost half of the Northern Hemisphere and mountainous regions worldwide with sufficient moisture and cold temperatures. Below 500: annually, but not in all of its territory. Snow develops in clouds that themselves are part of a larger weather system. The physics of snow crystal development in clouds results from a complex set of variables that include moisture content and temperatures. The resulting shapes of the falling and fallen crystals can be classified into a number of basic shapes and combinations thereof. Snow clouds usually occur in the context of larger weather systems, the most important of which is the low-pressure area, which typically incorporate warm and cold fronts as part of their circulation.
Mid-latitude cyclones are low-pressure areas which are capable of producing anything from cloudiness and mild snow storms to heavy blizzards. A warm front can produce snow for a period as warm, moist air overrides below-freezing air and creates precipitation at the boundary. Often, snow transitions to rain in the warm sector behind the front. The same effect occurring over bodies of salt water is termed ocean-effect or bay-effect snow. The effect is enhanced when the moving air mass is uplifted by the orographic influence of higher elevations on the downwind shores.
This uplifting can produce narrow but very intense bands of precipitation which may deposit at a rate of many inches of snow each hour, often resulting in a large amount of total snowfall. The areas affected by lake-effect snow are called snowbelts. Orographic or relief snowfall is created when moist air is forced up the windward side of mountain ranges by a large-scale wind flow. Mountain waves have also been found to help enhance precipitation amounts downwind of mountain ranges by enhancing the lift needed for condensation and precipitation. A snowflake consists of roughly 1019 water molecules which are added to its core at different rates and in different patterns depending on the changing temperature and humidity within the atmosphere that the snowflake falls through on its way to the ground. As a result, snowflakes differ from each other though they follow similar patterns.
