disturbance of the ordinary conditions of the atmosphere attended by wind, rain, snow, sleet, hail, or thunder and lightning. Types of storms include the extratropical cyclonecyclone,
atmospheric pressure distribution in which there is a low central pressure relative to the surrounding pressure. The resulting pressure gradient, combined with the Coriolis effect, causes air to circulate about the core of lowest pressure in a counterclockwise direction

tropical cyclone in which winds attain speeds greater than 74 mi (119 km) per hr. Wind speeds gust over 200 mi (320 km) per hr in some hurricanes. The term is often restricted to those storms occurring over the N Atlantic Ocean; the identical phenomenon occurring over

, which is somewhat smaller in area than the former and accompanied by high winds and heavy rains; the tornadotornado,
dark, funnel-shaped cloud containing violently rotating air that develops below a heavy cumulonimbus cloud mass and extends toward the earth. The funnel twists about, rises and falls, and where it reaches the earth causes great destruction.

violent, local atmospheric disturbance accompanied by lightning, thunder, and heavy rain, often by strong gusts of wind, and sometimes by hail. The typical thunderstorm caused by convection occurs when the sun's warmth has heated a large body of moist air near the

, local in nature and accompanied by brief but heavy rain showers and often by hail. The term storm is also applied to blizzardsblizzard,
winter storm characterized by high winds, low temperatures, and driving snow; according to the official definition given in 1958 by the U.S. Weather Bureau, the winds must exceed 35 mi (56 km) per hr and the temperature 20°F; (−7°C;) or lower.

A storm surge, sometimes called a tidal wave, is a flood of ocean or lake water that occurs in areas subject to tropical storms and bordering on shallow waters, but any strong low-pressure system in a coastal area, such as a northeaster along the Atlantic coast of North America, may produce a storm surge. Storm surges are due mostly to wind, which pushes the water ahead of a storm. In Galveston, Tex., in 1900 a hurricane with a wind velocity of more than 100 mi (160 km) per hr caused an ocean storm surge 15 ft (5 m) above normal high tide levels that flooded coastal areas, resulting in the loss of thousands of lives and extensive property damage. The highest storm surge on record in the United States is that caused by Hurricane Katrina (2005), which had sustained winds at landfall in SE Louisiana of more than 140 mi (225 km) per hr and a storm surge that by one estimate reached 29 ft (8.8 m) on the SW Mississippi coast and caused coastal devastation from SE Louisiana to Alabama.

an assault upon an enemy force defending a population point such as a fortress or a large city or upon enemy forces defending positions they have fortified strongly. Pillboxes, individual strongpoints, and fortified buildings are usually attacked by specially trained storm detachments or groups, which are formed from subunits of various branches of the armed forces or from special troops.

What does it mean when you dream about a storm?

Taking shelter from a storm indicates that whatever disturbance is occurring in the dreamer’s business or personal life will quickly blow over.

An atmospheric disturbance involving perturbations of the prevailing pressure and wind fields on scales ranging from tornadoes (0.6 mile or 1 kilometer across) to extratropical cyclones (up to 1800 miles or 3000 kilometers across); also the associated weather (rain storm or blizzard) and the like.

An abnormal and usually violent disturbance of, or condition in, the atmosphere, accompanied by wind, rain, dust, hail, or the like. The wind force in a storm is between 48 and 55 knots. A storm is termed “violent” if the wind speed is between 56 and 63 knots, and it becomes “hurricane force” if the speed is greater than 64 knots.

Blackberry Storm

The first touchscreen BlackBerry phone. Introduced in 2008, the Storm was a dual-band phone that supported both CDMA and GSM carriers. The original Storm touchscreen featured SurePress technology, which required an actual depression of screen keys. In late 2009, the Storm2 replaced SurePress with a multitouch screen similar to other smartphones. The Storm2 also had Wi-Fi, which was absent on the first model. By no means did the Storm take the world by storm. Several years later, the BlackBerry Z10 offered a vast improvement in functionality. See BlackBerry 10.

The BlackBerry Storm
The Storm was the first smartphone to combine features such as a three-megapixel camera, built-in GPS, a multi-format media player and support for both CDMA and GSM carriers. (Image courtesy of BlackBerry,

Everything in our life is a reflection on us and this holds true in our dreams. The storm in your dreams may be a reflection of some difficulty in your life. Consider all of the details and notice if you took shelter from the storm or were you swept away by it. Did the storm pass you by, were you safe, or did you suffer? All of us experience difficulties in life and our dreams make an attempt to bring us into awareness and out of denial. Think about the storms in your life, how you will weather them, and what you can do to make them subside.
