Along with global climate change, the occurrence of extreme droughts in recent years has had a serious impact on the Amazon region. Current studies on the driving factors of the and Amazon droughts has focused on the influence of precipitation, whereas the impacts of temperature and radiation have received less attention. This study aims to explore the climate-driven factors of Amazonian vegetation decline during the extreme droughts using vegetation index, precipitation, temperature and radiation datasets.
Since malaria epidemics have occurred in multiple sites in western Kenya highlands. Climatic variability has been associated with some of the recent epidemics. We examined influences of climatic factors on the distribution and abundance of three malaria vector species, Anopheles gambiae, Anopheles arabiensis , and Anopheles funestus in western Kenya and in the Great Rift Valley. Mosquito samples were collected from the lowland and highland areas with various climatic conditions. The three vector species were abundant in the lower part of western Kenya.

The most commonly used indicator of thermal comfort is air temperature — it is easy to use and most people can relate to it. However, air temperature alone is not a valid or accurate indicator of thermal comfort or thermal stress. It should always be considered in relation to other environmental and personal factors. The six factors affecting thermal comfort are both environmental and personal.
The term usually applies to the surfaces of terrestrial and glaciated environments , but it could also pertain to the surfaces of oceans and other bodies of water. The strongest gradients of temperature and humidity occur just above and below the terrestrial surface. Complexities of microclimate are necessary for the existence of a variety of life forms because, although any single species may tolerate only a limited range of climate , strongly contrasting microclimates in close proximity provide a total environment in which many species of flora and fauna can coexist and interact. Microclimatic conditions depend on such factors as temperature, humidity, wind and turbulence, dew, frost, heat balance, and evaporation. The effect of soil type on microclimates is considerable. Sandy soils and other coarse, loose, and dry soils, for example, are subject to high maximum and low minimum surface temperatures. The surface reflection characteristics of soils are also important; soils of lighter colour reflect more and respond less to daily heating.
Climatic factors include those environmental influences, such as temperature, humidity, atmospheric ionization, light and other forms of radiation, which in the final analysis are the result of solar radiations on the earth, its waters, and its atmosphere. The climatic differences from the equator to the poles are due chiefly to the amount of solar radiation received throughout the year and at different times during the year. Seasonal changes in climate are due to the inclination of the earth's axis from an angle perpendicular to its plane of rotation around the sun. These climatic factors and seasonal changes are generally quite dependable in their constancy for any one place on the earth's surface. Studies by C. Abbott of the Smithsonian Institution have shown that solar radiations may vary as much as 10 per cent but such extreme variations are seldom reflected more than fractionally by such climatic factors as temperature, due to the equalizing effects of atmosphere, winds, bodies of water, and latent heat.
Physical impacts of climate change
Skip to content. Skip to navigation. There are many different factors that affect climate around the world. The most important natural factors are:. It is now widely accepted that human activity is also affecting climate, and that the impact is not the same everywhere. For example, changes appear to be happening faster near the poles than in many other places. The sea affects the climate of a place.
An attempt has been made in this paper to study the effect of climatic factors on the growth of annually pruned tea and its components, the early crop, during April to June, the main crop during July to September and the late crop during October to December in northeast India. Data from two sources have been considered in this study, i long-term crop and weather data from the Tocklai experimental station and ii short-term data from tea-estates where the rainfall distribution is similar to that at Tocklai. A multiple regression of the yield of tea during a season on a number of independent climatic variables and age was fitted by the method of least squares and the independent variables were reduced step by step by the method of backward elimination until a set of critical variables associated with yield were obtained. Of all the climatic factors at Tocklai, rainfall up to 18 cm and the rise in mean temperature during the cold weather, i. There was also some direct beneficial effect of January to March rainfall on the main crop.
3.1 Factors affecting climate
The atmosphere is a dynamic fluid that is continually in motion. Both its physical properties and its rate and direction of motion are influenced by a variety of factors, including solar radiation , the geographic position of continents , ocean currents , the location and orientation of mountain ranges, atmospheric chemistry , and vegetation growing on the land surface. All these factors change through time. Some factors, such as the distribution of heat within the oceans , atmospheric chemistry, and surface vegetation, change at very short timescales. Others, such as the position of continents and the location and height of mountain ranges, change over very long timescales.
During the course of global warming, the energy balance and thus the temperature of the earth change, due to the increased concentration of greenhouse gases, which has a significant impact on humans and the environment. It is not scientifically possible to assign individual weather events to the current climate change, however, it can be statistically proven that global warming will increase the probability of extreme weather events. The indirect consequences of climate change, which directly affect us humans and our environment, include:. As the global climate is a highly interconnected system that is influenced by many different factors, the consequences usually result in positive or negative feedback effects.
Climate change causes a variety of physical impacts on the climate system. The physical impacts of climate change foremost include globally rising temperatures of the lower atmosphere, the land, and oceans. Temperature rise is not uniform, with land masses and the Arctic region warming faster than the global average. Effects on weather encompass increased heavy precipitation , reduced amounts of cold days, increase in heat waves and various effects on tropical cyclones. The enhanced greenhouse effect causes the higher part of the atmosphere, the stratosphere , to cool.
Сьюзан, - тихо сказал Стратмор.
Он двигался методично, обходя один ряд за другим. Наверху лениво раскачивалась курильница, описывая широкую дугу. Прекрасное место для смерти, - подумал Халохот. - Надеюсь, удача не оставит. Беккер опустился на колени на холодный каменный пол и низко наклонил голову. Человек, сидевший рядом, посмотрел на него в недоумении: так не принято было вести себя в храме Божьем. - Enferno, - извиняясь, сказал Беккер.
Коммандер был вынужден принимать невероятные решения, совершать чудовищные поступки, на которые, как ему казалось раньше, не был способен. Это единственное решение. Единственное, что остается. Нужно было думать о долге - о стране и о чести. Стратмор полагал, что у него еще есть время. Он мог отключить ТРАНСТЕКСТ, мог, используя кольцо, спасти драгоценную базу данных. Да, подумал он, время еще .
Он избранник богов. - В моих руках копия ключа Цифровой крепости, - послышался голос с американским акцентом. - Не желаете купить.
Он направил мотоцикл через кустарник и, спрыгнув на нем с бордюрного камня, оказался на асфальте. Веспа внезапно взбодрилась. Под колесами быстро побежала авеню Луис Монтоно. Слева остался футбольный стадион, впереди не было ни одной машины.
