These environmental factors control the distribution of plants and animals across different parts of the earth and in turn affect the behavior and activities of man.

Weather is the condition of the atmosphere at a particular place over a short period of time, whereas climate refers to the weather pattern, using statistical data, of a place over a long enough period to yield meaningful averages. Climate is an important element because it indicates the atmospheric condition of heat, moisture and circulation; it plays a dominant role in shaping vegetation and soil; and it ultimately affects all forms of life, as a result of the very definition of the word, which is a scientific prediction, based on evidentiary statistics, sustained over a long period. There are many elements that make up both the weather and the climate of a geographical location. The most significant of these elements are temperature , atmospheric pressure , wind , solar irradiance , humidity , precipitation , condensation and topography.

Importance of Weather Monitoring in Farm Production

Weather is something we all care about. Not only do we are hope for warm, sunny weather so that we can swim, enjoy nature, or operate important farm activities but sometimes we wish for the rain to simply water the plants or dance with an umbrella on the wet street. However, unlike other industries, the weather is the most important element that affects farm production. It can influence crop growth, total yield, pest occurrence, water and fertilizer need, and all farm activities carried out during the growing season. In other words, farming under the open sky is greatly reliant upon the weathe r and is subject to its moody conditions, especially nowadays, when climate change leads to unpredictable weather which is beyond human control. However, he can adopt the given situation and take additional farm management practices to minimize crop losses.

This chapter discusses ways in which society is becoming increasingly sensitive to weather and climate. At the same time, better understanding, observations, and numerical models are leading to improvements in the accuracy of weather and climate information. Together, the increased sensitivity and the availability of more accurate information are creating more and new users of environmental information and are heightening the value of this information. Satellites provide an essential component of a global observing system that serves as a foundation for an Earth Information System, a comprehensive environmental database that will support a large variety of users for the benefit of society. The trends highlighted above call for a more rapid transitioning of NASA research to NOAA operations in order to increase the rate of return to society from the public investment in research.

Weather and climate

Weather is the state of the atmosphere , describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy. Weather refers to day-to-day temperature and precipitation activity, whereas climate is the term for the averaging of atmospheric conditions over longer periods of time. Weather is driven by air pressure , temperature , and moisture differences between one place and another. These differences can occur due to the Sun's angle at any particular spot, which varies with latitude. The strong temperature contrast between polar and tropical air gives rise to the largest scale atmospheric circulations : the Hadley cell , the Ferrel cell , the polar cell , and the jet stream. Weather systems in the middle latitudes , such as extratropical cyclones , are caused by instabilities of the jet streamflow. Because Earth's axis is tilted relative to its orbital plane called the ecliptic , sunlight is incident at different angles at different times of the year.

The types of weather a region receives depends on its climate, or long-term weather characteristics. Some regions are hot and arid, while others are temperate and humid. The benefits of weather and climate depend on the region, but there are some consistencies across the globe. From producing rainfall to creating the perfect places to mine for metals, climate and weather determine the way humans interact with their world. Perhaps the most obvious and the most important benefit of weather and climate is that they bring rain, snow and other forms of precipitation.

Weather and Climate Differences, Similarities and Importance

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.

Increasing temperatures caused by climate change will make the water of the oceans expand; ice melting in the Antarctic and Greenland will also contribute to the sea level. Sea levels could rise by as much as 25 to 50 cm, by

Сьюзан попыталась осознать то, что ей сообщил коммандер. Она сомневалась, что Танкадо мог передать ключ какому-то человеку, который не приходился ему близким другом, и вспомнила, что в Штатах у него практически не было друзей. - Северная Дакота, - вслух произнесла она, пытаясь своим умом криптографа проникнуть в скрытый смысл этого имени.  - Что говорится в его посланиях на имя Танкадо. - Понятия не имею.
