Summer is the most favorite time of the year at the school and their parents.It is time the long-awaited vacation and holidays.Summer is characterized by an increase in temperature up to the maximum possible performance, and distinctive features, the phenomena of nature.This season lasts three months.Nevertheless, various latitudes it occurs differently.In the southern hemisphere the summer months are December, January and February.In the north of the Equator this time of year is distributed in June, July and August.In cold countries, the warm season can last no longer than one month.
Natural phenomena summer
Each season is characterized by certain climatic conditions.In winter snows, frosts occur;Spring begins to blossom trees, the birds, there is a flood;autumn leaf fall we see, constant rainfall.But a phenomenon observed in nature, characterized by summer?This time of year is determined by several meteorological changes.
All summer natural phenomena (examples: thunderstorm, dew, the rainbow and so on.) Are associated with a significant warming.This time of year the weather is sultry, dry, though for a man it is considered favorable.It should be noted that highly variable summer weather phenomena of nature.Examples: rain, hail, wind.In the days when the sun shines brightly and the sky, a few minutes can get together and cumulus clouds to the real storm with thunder and lightning.In the case of short-lived shower of half an hour the temperature rises again, and the sun will continue to strongly svetit.Osadki summer are always in short range, but they have a high intensity.Along with thunderstorms often rises sharply with the strong wind gusts.After rain can often see this phenomenon, like a rainbow.In the morning, often acts as the dew.
Wind
This natural anomaly is a stream of air that is directed mainly to the horizontal surface of the earth.Wind classified for power, speed, scale, the level of distribution.For certain categories of anomalies should be considered its strength, duration and direction.
On land in the summer the winds are only a squall during a severe thunderstorm or in front of it.This is due to the collision of two opposing temperature and direction of air masses in the different layers of the atmosphere.In the Americas, often at this time of year there are powerful hurricanes.What is the phenomenon observed in nature in the summer, it happens in the waters of the sea or the ocean?They are most often short storms, which are different intensity and strong gusts of wind.Often they raise wave height of several meters.
noteworthy that changes in seasonal temperature indicators winds are important global monsoons.Their duration varies within a few months.Monsoons have different circulation and temperature, strength and direction.It depends on them, what would be the time of year: warm or cold.
Clouds
a result of condensation of water vapor rises into the upper atmosphere.Crystallized particles under the influence of low temperatures and in the combined air masses.This is how clouds form in the sky (see photo natural phenomena. Below) .Each cloud consists of particles of water and has a unique shape that is changing under the influence of air flow and temperature.If the upper atmosphere temperature of -100 degrees Celsius, the clouds are composed of elements drip.Otherwise, they will dominate the composition of the ice crystals.
Summer Clouds are divided into lightning, rain, cumulus, cirrus, stratus and others.If the air element is connected to the cloud, there is a strong possibility of precipitation.Most heavy rains fall from layered and cumulus clouds.If the air mass has a uniform composition, the rainfall will be small and short-term.
Rain
In the hot season rainfall are considered quite rare climatic anomalies.By itself, the rain is a continuous drop in the water vertically.The starting point of the movement are the clouds.Rain - the cumulative nature of the phenomenon.While the clouds will not gain a lot of moisture, precipitation starts.
Today to distinguish between five kinds of summer rains:
1. Ordinary.Drops without such a bright featureless as power or duration.2. The short-term.Its main feature is considered to be fleeting.Such natural phenomena as a summer read, and ends suddenly.
3. Mushroom.Precipitation determined by low intensity and transience.During the rain the sun continues to shine.
4. Showers.Determined suddenness.Within a short period with great power on the ground falls out a lot of water.Livni, often accompanied by strong winds, lightning and thunder.In the summer, the rain is called rain.
5. Gradoobrazny.Together with the water droplets fall to the ground ice particles of different sizes.Such sediments are characterized by transience and power have a negative impact on agriculture.
Grad
Mixed cloudy iced require special attention because of their danger to property and sometimes human lives.Hail is a type of precipitation that falls to the ground frozen water.Not to be confused with a mixture of rain and snow.Here is a link ice particles can reach sizes of up to several centimeters.Grad has high strength and transparency (natural phenomena pictures you can see below).This makes it dangerous for small animals and birds, as well as for larger osobey.Osadki this type of fall during the storm of the largest cumulus clouds.In turn, the clouds are different in black or gray color, and white tops.Hail is formed in ordinary rain clouds as a result of supercooled droplets of moisture.Ice particles are gradually increased, are bonded to each other.Precipitation hail may last from a few minutes to half an hour.Large icicles can completely destroy entire crops cultures.
Thunderstorm
This meteorological phenomenon refers to the most powerful type of precipitation zero temperature.Rain and hail and thunder - summer phenomena of nature, which is assigned to the orange level of danger.Such rainfall accompanied by strong wind gusts sharp, sometimes a squall.
distinctive climatic features thunderstorms are lightning and thunder.Powerful electric charge emitted from the cloud to the surface.Lightning is formed in the atmosphere due to the collision of positive and negative charges.As a result, electromagnetic induction occurs in the hundreds of millions of volts.When the charging voltage reaches a maximum stroke of lightning is formed.
Thunder is a consequence of the rapid expansion of the air as a result of heating the particles around a sharp electromagnetic arc.The sound waves bounce off of clouds and causes a strong echo.
Rainbow
Today it is one of the most amazing and wonderful natural anomalies associated with precipitation.Rainbow - a phenomenon that may occur after the rain, and in the process or before it.The formation of the phenomenon depends on the movement of storm oblakov.Tsvetovaya gamma rainbow is reflected at an angle of 42 degrees.The arc is visible through the curtain of rain on the opposite side of the sun.The spectrum of the rainbow is represented by seven colors.That's the number of components from sunlight.Mostly this phenomenon is the result of short-term precipitation in the summer.
human eye detects colors of the rainbow after the rain, which act as prisms.It's kind of a wide range of natural origin.
Rosa
In calm weather as a result of cooling at night and in the morning with the first warming rays of the sun on the surface of the earth, grass, flowers and other plants and objects are formed droplets of water.This weather phenomenon is called dew.
At night, the earth's surface cooled.As a result, the steam begins to condense in the air and turns into water, settling on objects.It is believed that the dew formed only under clear skies and light winds.It should be noted that the lower the temperature behavior, the more likely this will kapelki.Chasche phenomenon formed in the tropics, where it is accompanied by humid climate and long cold nights.
Summer natural phenomena.Examples: class 2
in school curricula introductory basics of climate anomalies are studying from textbooks "The world around us."The first lessons are held since the second grade.At these classes talk about what a summer phenomena of nature, what are their characteristics and features.
Introducing the seasons should proceed with the inclusion in the program examples available.In the summer it gets warmer, the days are longer, the nights shorter, birds begin to sing, go mushroom showers, water in rivers and lakes warms, the grass is green and so on.
For children eight years of summer natural phenomena are a mystery.Therefore, be sure to support the theory of practice.To do this, we conducted a variety of excursions.In June you can acquaint children with summer flowers, trees, insects, birds.July - a good time to walk through the arboretum or the woods, where you can listen to the sounds of nature.In August, no harm will be familiar with berries, mushrooms, fruit trees.
Signs of summer events
- When the south wind blows, you should wait for bad weather if the western, it will soon be cooling.
- for quick termination of a severe thunderstorm should be thrown out the window toward the direction of the rain broom.
- A lit object after a lightning strike to put out is impossible, as there is burning hell.
- Long wind with constant gusts - a drowned man.
- If thunder is heard from the north, the summer is expected to be cold when the peals are heard in the south, so it will be hot.
- If large bubbles are formed puddles from the rain, it's a strong storm.
There are signs of natural phenomena on the rainbow:
- If the arc is complete and high worth waiting warming.
- Green Rainbow - for a long downpour, red - to the heavy wind, yellow - to the calm.
