School Closing
A weather cancellation or delay is closure, cancellation, or delay of an institution, operation, or event as a result of inclement weather. Certain institutions, such as schools, are likely to close when bad weather, such as snow, flooding, air pollution, tropical cyclones, or extreme heat or cold impairs travel, causes power outages, or otherwise impedes public safety or makes opening the facility impossible or more difficult. Depending upon the local climate, the chances of a school or school system closing may vary. While some regions may close or delay schools when there is any question of safety, others located in areas where bad weather is a regular occurrence may remain open, as local people may be accustomed to travelling under such conditions. Many countries and sub-national jurisdictions have mandates for a minimum number of school days in a year. To meet these requirements, many schools that face a likelihood of closure build a few extra school days into their calenda ...

Severe Weather
Severe weather is any dangerous meteorological phenomenon with the potential to cause damage, serious social disruption, or loss of human life. Types of severe weather phenomena vary, depending on the latitude, altitude, topography, and atmospheric conditions. High winds, hail, excessive precipitation, and wildfires are forms and effects of severe weather, as are thunderstorms, downbursts, tornadoes, waterspouts, tropical cyclones, and extratropical cyclones. Regional and seasonal severe weather phenomena include blizzards (snowstorms), ice storms, and duststorms. Extreme weather phenomena which cause extreme heat, cold, wetness or drought often will bring severe weather events. One of the principal effects of anthropogenic climate change is changes in severe and extreme weather patterns. Terminology Meteorologists have generally defined severe weather as any aspect of the weather that poses risks to life, property or requires the intervention of authorities. A narrower ...

School Year
A school is an educational institution designed to provide learning spaces and learning environments for the teaching of students under the direction of teachers. Most countries have systems of formal education, which is sometimes compulsory. In these systems, students progress through a series of schools. The names for these schools vary by country (discussed in the '' Regional terms'' section below) but generally include primary school for young children and secondary school for teenagers who have completed primary education. An institution where higher education is taught is commonly called a university college or university. In addition to these core schools, students in a given country may also attend schools before and after primary (elementary in the U.S.) and secondary (middle school in the U.S.) education. Kindergarten or preschool provide some schooling to very young children (typically ages 3–5). University, vocational school, college or seminary may be availabl ...

Air Conditioning
Air conditioning, often abbreviated as A/C or AC, is the process of removing heat from an enclosed space to achieve a more comfortable interior environment (sometimes referred to as 'comfort cooling') and in some cases also strictly controlling the humidity of internal air. Air conditioning can be achieved using a mechanical 'air conditioner' or alternatively a variety of other methods, including passive cooling or ventilative cooling. Air conditioning is a member of a family of systems and techniques that provide heating, ventilation, and air conditioning (HVAC). Heat pumps are similar in many ways to air conditioners, but use a reversing valve to allow them to both heat and also cool an enclosed space. Air conditioners, which typically use vapor-compression refrigeration, range in size from small units used within vehicles or single rooms to massive units that can cool large buildings. Air source heat pumps, which can be used for heating as well as cooling, are becoming incre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bomb Threat
A bomb threat or bomb scare is a threat, usually verbal or written, to detonate an explosive or incendiary device to cause property damage, death, injuries, and/or incite fear, whether or not such a device actually exists. History Bomb threats were used to incite fear and violence during the American Civil Rights Movement, during which leader of the movement Martin Luther King Jr. received multiple bomb threats during public addresses, and schools forced to integrate faced strong opposition, resulting in 43 bomb threats against Central High School in Arkansas being broadcast on TV and the radio. Motivations Supposed motives for bomb threats include: "humor, self assertion, anger, manipulation, aggression, hate and devaluation, omnipotence, fantasy, psychotic distortion, ideology, retaliation," and creating chaos. Many of the motives based on personal emotion are speculative. Many bomb threats that are not pranks are made as parts of other crimes, such as extortion, arson, o ...

Terrorist Attack
Terrorism, in its broadest sense, is the use of criminal violence to provoke a state of terror or fear, mostly with the intention to achieve political or religious aims. The term is used in this regard primarily to refer to intentional violence during peacetime or in the context of war against non-combatants (mostly civilians and neutral military personnel). The terms "terrorist" and "terrorism" originated during the French Revolution of the late 18th century but became widely used internationally and gained worldwide attention in the 1970s during the Troubles in Northern Ireland, the Basque conflict, and the Israeli–Palestinian conflict. The increased use of suicide attacks from the 1980s onwards was typified by the 2001 September 11 attacks in the United States. There are various different definitions of terrorism, with no universal agreement about it. Terrorism is a charged term. It is often used with the connotation of something that is "morally wrong". Governments and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Failure
A power outage (also called a powercut, a power out, a power failure, a power blackout, a power loss, or a blackout) is the loss of the electrical power network supply to an end user. There are many causes of power failures in an electricity network. Examples of these causes include faults at power stations, damage to electric transmission lines, substations or other parts of the distribution system, a short circuit, cascading failure, fuse or circuit breaker operation. Power failures are particularly critical at sites where the environment and public safety are at risk. Institutions such as hospitals, sewage treatment plants, and mines will usually have backup power sources such as standby generators, which will automatically start up when electrical power is lost. Other critical systems, such as telecommunication, are also required to have emergency power. The battery room of a telephone exchange usually has arrays of lead–acid batteries for backup and also a socket f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
