Which group of natural disasters include hurricanes, tornadoes, and storms?

What is wind?

(Wind is the movement of air relative to the earth's surface resulting from the uneven distribution of atmospheric pressure in a low pressure zone)

- What do you think characterizes the wind?

(direction, speed, force)

Wind force is measured by the Beaufort scale

Child's message about the Bafort scale

What do you think is an atmospheric front, and what types of air masses are there?

An atmospheric front is the separation between two air masses

Types of atmospheric fronts

cold - the speed of cold air is higher than the speed of warm air

warm – the speed of warm is higher than the speed of cold

occlusion front – does not represent clear boundaries where cyclones arise

A cyclone is a vortex movement of air counterclockwise

Consider the types of winds

Hurricanes happen: severe hurricanes over 170 km/h

Severe hurricanes 140-170 km/h

Hurricane 120 – 140 km/h

There are storms: dusty, snowy, squally

There are tornadoes: small tornadoes of short duration up to 1 km.

Small tornadoes up to 10 km

Hurricane tornadoes over 10 km

Presentation on the topic: “Hurricanes, storms, tornadoes” Compiled by life safety teacher Baranova N.V.

Introduction The territory of any region is subject to the complex effects of dozens of dangerous natural phenomena. The most typical natural phenomena in terms of frequency depending on the time of year and leading to emergencies are hurricanes, storms and tornadoes. Let's consider these phenomena. The photo shows a view of the storm from space.

Hurricane A hurricane is a large atmospheric vortex with wind speeds of up to 120 km/h, and in the squat layer up to 200 km/h.

Storm Storm is a type of hurricane and storm. Hurricanes and storms differ in wind speed, which during a hurricane reaches 120 km/h or more, and during a storm 60 - 10 0 km/h. The losses from a hurricane are greater than from a storm.

A tornado is an atmospheric vortex that arises in a thundercloud and spreads down to the ground in the form of a dark cloud arm or trunk with a diameter of tens and hundreds of meters. It does not exist for long, moving along with the cloud. Tornado

Danger from these phenomena Destruction of road and bridge surfaces Destruction of structures and buildings Objects flying at high speed The photo shows the consequences of a hurricane

How to act before a hurricane, storm, tornado. After receiving a storm warning signal, proceed to: strengthening the roof, stove and ventilation pipes; sealing windows in attics (shutters, panels made of boards or plywood); clearing balconies and courtyard areas from fire hazards; to collect supplies of food and water for 2-3 days in case of evacuation to a safe area, as well as autonomous lighting sources (lanterns, kerosene lamps, candles); move from light buildings to more durable buildings or civil defense structures.

How to act during a hurricane, storm, tornado. In a building, move away from windows and take a safe place near the interior walls. Extinguish the fire in the stoves, turn off the electricity, close the taps on the gas networks. In the dark, use lanterns, lamps, and candles. Turn on the radio to receive information from the Civil Defense and Emergency Management and the Commission for Emergency Situations. If possible, be in a buried shelter, in shelters, in cellars, etc. On the streets of a populated area, stay as far as possible from light buildings, buildings, bridges, overpasses, power lines. To protect against flying debris and glass shards, use sheets of plywood, cardboard and plastic boxes, boards and other available means.

How to act during a hurricane, storm, tornado. When you receive a signal that a tornado is approaching, you must immediately go down to a shelter, the basement of a house or a cellar. If a tornado catches you in an open area, take shelter at the bottom of a road ditch, in holes, ditches, narrow ravines, pressing tightly to the ground. Do not stay in the vehicle, get out and take shelter as described above.

After a hurricane, storm, or tornado: Be careful when walking around downed wires. Beware of fallen trees, swaying shutters, signs, banners, gas leaks in the house, electrical problems (use electric lights before checking). Electrical appliances can only be used after they have been dried and checked. If the storm is accompanied by thunder, avoid electrical shock.

Consequences The consequences of hurricanes, storms and tornadoes are floods, destruction of buildings, disruption of living conditions of the population.

Consequences Powerful hurricanes with rain, storms and tornadoes often lead to casualties. A large number of public, economic and industrial facilities and residential buildings are damaged. The damage could reach billions of rubles.

Summer 2002 Crimean coast. Windows and doors were broken in apartments, and the roofs of hundreds of houses were torn off. The wind knocked down trees, bent traffic lights and street lighting poles, as if it were dealing with toys from newsstands and food stalls. The electricity and heat supply failed. People found themselves without light, water and heat. Television and radio broadcasting fell silent. It was impossible to convey the necessary information to the population. Mudflows that came down from the mountains washed campsites into the sea along with cars, tents and people.

Summary The most common natural disasters in Europe are storms, hurricanes and, as a consequence, floods. In terms of economic losses and the volume of subsequent insurance payments, hurricanes and floods are the most financially significant. Hurricanes Lota and Martin in December 1999 caused damage estimated at €5 billion, damaging crops, forests and community infrastructure.

Introduction
The territory of any region is subject to the complex effects of dozens of dangerous natural phenomena. The most typical natural phenomena in terms of frequency depending on the time of year and leading to emergencies are hurricanes, storms and tornadoes. Let's consider these phenomena. The photo shows a view of the storm from space.

Hurricane
A hurricane is a large atmospheric vortex with wind speeds of up to 120 km/h, and in the low-lying layer up to 200 km/h.

Slide 4

Storm
A storm is a type of hurricane and storm. Hurricanes and storms differ in wind speed, which during a hurricane reaches 120 km/h or more, and during a storm 60-100 km/h. The losses from a hurricane are greater than from a storm.

Slide 7

How to act before a hurricane, storm, tornado.
After receiving a storm warning signal, proceed to: strengthening the roof, stove and ventilation pipes; sealing windows in attics (shutters, panels made of boards or plywood); clearing balconies and courtyard areas from fire hazards; to collect supplies of food and water for 2-3 days in case of evacuation to a safe area, as well as autonomous lighting sources (lanterns, kerosene lamps, candles); move from light buildings to more durable buildings or civil defense structures.

Slide 8

In a building, move away from windows and take a safe place near the interior walls. Extinguish the fire in the stoves, turn off the electricity, close the taps on the gas networks. In the dark, use lanterns, lamps, and candles. Turn on the radio to receive information from the Civil Defense and Emergency Management and the Commission for Emergency Situations.
