Full featured rainbow in Wrangell-St. Elias National Park, Alaska.

A rainbow is an optical and meteorological phenomenon that causes a nearly continuous spectrum of light to appear in the sky when the Sun shines onto droplets of moisture in the Earth's atmosphere. It takes the form of a multicoloured arc, with red on the outside and violet on the inside. A double rainbow includes a second, fainter, arc with colors in the opposite order.

Atlantic hurricane reanalysis is an ongoing project within the National Oceanic and Atmospheric Administration which seeks to correct and add new information about past North Atlantic tropical cyclones. It was started around 2000 to update HURDAT, the official hurricane database for the Atlantic Basin, which has become outdated since its creation.

Meteorology and history

A European windstorm is a severe cyclonic storm that tracks across the North Atlantic towards northwestern Europe in the winter months. These storms usually track over the north coast of Scotland towards Norway but can veer south to affect other countries including Ireland, Wales, England, France, Belgium, the Netherlands, Denmark, Sweden and Germany. As these storms can generate hurricane-force winds (and sometimes even winds at the strength of major hurricanes), they are sometimes referred to as hurricanes, even though very few originate as tropical cyclones.

These storms cause economic damage of $1.7 billion U.S. per year, and insurance losses of $1.2 billion U.S. per year (1990-1998). They rank as the second highest cause of global natural catastrophe insurance loss (after U.S. hurricanes). [1]

Waterspouts on the beach of Kijkduin near The Hague, Netherlands on 27 August 2006.

Help to develop this portal. The major updates should appear every month. We are developing this portal slightly differently from the majority of portals by grouping all text in one page. Also, we try to coordinate between Polish and English editions (perhaps we could do this across other Wikis?)
