Содержание слайда: MEDITERRANEAN CLIMATE Average temperature of the coldest month is 0ºC, the warmest month temperature is +22+28ºC. The summer is hot and dry, sometimes the temperature reaches +42+45ºC due to hot winds (sirocco and mistral) from the North Africa deserts.

In winter dry continental tropical air prevails, brought by trade winds, in summer there is wet air from equator. That is why wet weather with heavy precipitations is frequent in summer, the highest average temperature per month is +25…+30ºC. But in winter the weather is dry, the lowest average month temperature is +15…..+18ºC.

There are deserts of Sahara, Libyan, Nubian, Namibia, Kalahari and also Arabia, South America and central part of Australia deserts. Common characteristic for deserts: Complete absence of cloudiness High solar radiation amount High air and ground temperature Dryness and high level of evaporation Limited or complete absence of water resources

Содержание слайда: In hot climate at weakened people at heavy physical work daily losses of water can reach 12 liters - thus can give dehydration of the organism different degree of weight. Thus plasma of blood first of all suffers. In hot climate at weakened people at heavy physical work daily losses of water can reach 12 liters - thus can give dehydration of the organism different degree of weight. Thus plasma of blood first of all suffers. Thus viscosity of blood, the contents of hemoglobin sharply raises, the volume of circulating blood decrease - reduction speed of blood circulation, reduction shock volume of heart, increase frequency of cardiac reductions.

Содержание слайда: HYGIENIC CHARACTERISTIC OF WATER RESOURCES AND SOURCES OF WATER SUPPLY IN TROPICAL REGIONS There is no water problem in humid tropics: area is covered by forests, jungle, frequent heavy rains, tropical storms constantly replenish surface and underground waters. There is significant water deficiency in arid areas especially in deserts, seasonal water changes into drought or rain absence create hard living conditions for living organisms or make life impossible.

Содержание слайда: Ground water – subterranean and artesian – doesn’t need purification and disinfection. In some cases softening, desalination and defluorination are necessary. Ground water – subterranean and artesian – doesn’t need purification and disinfection. In some cases softening, desalination and defluorination are necessary. Depending on size and pollution degree, surface water is able to self-purify because of suspected materials inclusion sedimentation, solar radiation, aeration (organic substances oxidation), dilution, biochemical oxidation, saprophytic microorganisms, bakteriophages action, nitri- and nitrofication. But reproduction of pathogenic organisms, viruses, infectious agents is possible in hot regions. In case of significant pollution water can decay and become unusable for domestic and drinking purposes.

Содержание слайда: The complex building and sun-protection measures is necessary: apartment houses are better for building near to green plantings and reservoirs, orientation of windows - to the north, building materials should be heatproof: tree, brick, foam concrete, pise-walled materials. Building with an attic with good isolation and aeration is necessary. It is expedient to increase the sizes of rooms and their height. Colouring of external walls is recommended light for reflection of solar radiation; special canopies, a venetian blind above windows.
