1995 Chicago Heat Wave
The July 1995 Chicago heat wave led to 739 heat-related deaths in Chicago over a period of five days. Most of the victims of the heat wave were elderly poor residents of the city, who could not afford air conditioning and did not open windows or sleep outside for fear of crime. The heat wave also heavily impacted the wider Midwestern region, with additional deaths in both St. Louis, Missouri and Milwaukee, Wisconsin. Weather The temperatures soared to record highs in July with the hottest weather occurring from July 12 to July 16. The high of on July 13 was the second warmest July temperature (warmest being set on July 23, 1934) since records began at Chicago Midway International Airport in 1928. Nighttime low temperatures were unusually high — in the upper 70s and lower 80s °F (about 26 °C). The humidity made a large difference for the heat in this heat wave when compared to the majority of those of the 1930s, 1988, 1976–78 and 1954–56, which were powered by ex ...

High Pressure System
A high-pressure area, high, or anticyclone, is an area near the surface of a planet where the atmospheric pressure is greater than the pressure in the surrounding regions. Highs are middle-scale meteorological features that result from interplays between the relatively larger-scale dynamics of an entire planet's atmospheric circulation. The strongest high-pressure areas result from masses of cold air which spread out from polar regions into cool neighboring regions. These highs weaken once they extend out over warmer bodies of water. Weaker—but more frequently occurring—are high-pressure areas caused by atmospheric subsidence: Air becomes cool enough to precipitate out its water vapor, and large masses of cooler, drier air descend from above. Within high-pressure areas, winds flow from where the pressure is highest, at the center of the area, toward the periphery where the pressure is lower. However, if the planet is rotating, the straight direction of the air flow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cooling Center
A cooling center is an air-conditioned public space set up by local authorities to temporarily deal with the health effects of extreme heat weather conditions, like the ones caused by heat waves. Cooling centers are meant to prevent hyperthermia caused by heat, humidity, and poor air quality. Cooling centers provide shade, water, and restrooms; medical attention and referrals to social services may also be offered. Their services are aimed at the homeless, those without access to adequate air conditioning and at-risk populations such as the elderly, children and those with mental disability or chronic medical conditions. As the danger of heat waves has risen in the public consciousness, cooling centers are increasingly used in larger cities such as Los Angeles, New York City, Chicago, Boston, and Toronto, as well as less urban population areas. Cooling centers may also be used in places like Portland and Seattle where home air conditioning is rare but summer can bring temperature ...

Ambulance
An ambulance is a medically equipped vehicle which transports patients to treatment facilities, such as hospitals. Typically, out-of-hospital medical care is provided to the patient during the transport. Ambulances are used to respond to medical emergencies by emergency medical services (EMS). For this purpose, they are generally equipped with flashing emergency vehicle lighting, warning lights and siren (noisemaker), sirens. They can rapidly transport paramedics and other first responders to the scene, carry equipment for administering emergency medicine, emergency care and transport patients to hospital or other definitive care. Most ambulances use a design based on vans or pickup trucks. Others take the form of Motorcycle ambulance, motorcycles, buses, limousines, Air medical services, aircraft and Water ambulance, boats. Generally, vehicles count as an ambulance if they can transport patients. However, it varies by jurisdiction as to whether a Patient transport, non-emerge ...

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] |
Urban Heat Island
An urban heat island (UHI) is an urban or metropolitan area that is significantly warmer than its surrounding rural areas due to human activities. The temperature difference is usually larger at night than during the day, and is most apparent when winds are weak. UHI is most noticeable during the summer and winter. The main cause of the UHI effect is from the modification of land surfaces. A study has shown that heat islands can be affected by proximity to different types of land cover, so that proximity to barren land causes urban land to become hotter and proximity to vegetation makes it cooler. Waste heat generated by energy usage is a secondary contributor. As a population center grows, it tends to expand its area and increase its average temperature. The term heat island is also used; the term can be used to refer to any area that is relatively hotter than the surrounding, but generally refers to human-disturbed areas. Monthly rainfall is greater downwind of cities, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
