Weather hazards 🌪️ Flashcards
Economic impact
the effect of an event on the wealth of an area or community.
environmental impact
the effect of an effect on a landscape and ecology of the surrounding area.
extreme weather
when a weather event is significantly different in comparison to usual weather patterns and is especially severe + unseasonal. could take place in one day or a period of time.
Example in UK: severe snow blizzard, heat wave.
Global atmospheric cirulation
worldwide system of winds, which transports heat from tropical to polar latitudes. In each hemisphere, air also circulates in the entire depth of the troposphere (15 km)
immediate responses
the reaction of people as the disaster happens and the immediate aftermath
long-term responses
later reaction that occur in the weeks, moths and years
management strategies
techniques of controlling, responding to or dealing with an event
monitoring
recording physical changes such as tracking a tropical storm by satellite, helps forecast where and when a natural hazard may happen.
planning
actions taken to enable communities to respond to, and recover from the natural disasters through measures such as emergency evacuation plans, info management, communications and warning systems
prediction
attempts to forecast where and when the natural hazard may occur based off of current knowledge ( tropical storms, eruptions, less reliable for earthquakes)
primary effects
actions taken before a hazard strikes to reduce the impact, such as educating people and improving building structures
protection
actions taken before hazard strikes to reduce the impact ( education, structure improvement)
secondary effects
the after effects that occur as indirect impacts of a natural event, sometimes on a longer timescale, for instance impact on access to potable water can lead to spread of disease
social impact
the effect of an event on the lives of people or community
tropical storm ( hurricane, cyclone, typhoon)
an area of low pressure winds moving in a spiral around the calm central point called the eye of the storm, powerful winds, heavy rain.
