The Global System's Effect on Climates
The global pattern of climate is affected by:
* latitude
* land and sea
* relief
* ocean currents
Latitude
========
The Equator receives greater amounts of solar heating than latitudes
further north or south. Places therefore nearer the Equator are much
warmer than those closer to the Poles. Nearer the Poles precipitation
will be more variable with lower temperatures. More will fall as snow,
covering the ground for long periods in winter.
The amount of solar energy received by each hemisphere varies because
of the tilt of the Earth and its orbit around the sun. This gives
summer and winter seasons. Places nearer the Poles have greater
differences between summer and winter in temperature and
precipitation.
At the Equator air, warmed from below, becomes less dense and is
forced to rise as strong convection currents, creating low pressure at
the surface (ITCZ). Convectional currents of warm, moist air cool to
give heavy, daily thunderstorms
Strong, steady winds converge to fill the low pressure from the north
and south, but the spinning of the Earth diverts the winds slightly to
the right in the northern hemisphere and they become the north-east
Trade Winds. In the southern hemisphere winds are diverted to the
left, producing the south-west Trade Winds.
Air in the upper atmosphere flows away from the Equator and cools.
Cooling air becomes denser, heavier and descends back to the surface
on the polar sides of the 'Cell', causing zones of high pressure at
about 30° north and south of the Equator (sub-tropical high pressure
zone). Descending a...

Prevailing winds from the south west, passing over the ocean current
are warmed and pick up large amounts of moisture. The precipitation,
caused when the air is forced to rise over mountains or at fronts,
provides the British Isles with a reliable precipitation all year.
Cold ocean currents from colder polar waters have a contrasting
effect. Those flowing south along coasts in the northern hemisphere
keep summer temperatures cooler and the air drier than normal for that
latitude. Coastal fogs occur when warmer air from over the land is
cooled by the cold water.
In tropical areas warm ocean currents, such as the Kuro Siwo which
flows north towards Japan, are the source of the large amounts of
energy and moisture that can result in the development of intense
depressions or typhoons.
Scientists have determined that weather systems are changeable. Over a large amount of time, the earths tilt changes, causing the axis’s to tilt more one way then it used to, and thus changing the weather. Greenhouse gasses may also change the weather, making our climate either much hotter or much cooler. Ice caps and deserts have one thing in common, one small change in the weather can change them- and they will change the world.

Impacts of Artificial Climate Modification Controlling the weather. The very idea of it sounds enthralling and, yet, terrifying. Take a moment and think about the endless possibilities. Imagine the scenario: Hurricane Katrina is headed straight for Louisiana, Mississippi, and Texas.
“In the last three decades, the United States has had an average of 80% consumption of fossil fuels such as coal, gas and oil; all of which contribute to the emission of greenhouse gases” (Josef). All over the world, climate is varied; however, that is not the problem. The problem is that our climate and weather patterns are changing and leaving disaster and catastrophe in its wake. The common question of debate is whether humans are the main cause of this climate change, if it is solely a natural occurrence, and what can we do about it? “Climate change refers to any significant change in the measures of climate lasting for an extended period of time. In other words, climate change includes major changes in temperature, precipitation, or wind
Earth’s natural energy balance is the process by which incoming solar radiation from the sun is reflected, absorbed, and contained. By doing this, the solar radiation is spread across the earth. Everything from clouds to greenhouse gases will impact how much solar radiation will reach earth and what is reflected either back into space or sent back down to earth again if trapped.
Climate change, is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time. These times can be anywhere from decades to millions of years. The Earth’s climate has constantly been changing throughout history. Climate change can be dated back to over 650,000 years ago. Most of the changes that happened before 7,000 years ago happened because of small variations in Earth’s orbit that change the amount of solar energy the earth planet receives. Even though climate change is natural, people are speeding up the process at which it occurs by polluting. Climate change has many impacts all over the world and its effects are evident. People can still slow down the process at which climate change
Leading to our planets slow demise, global climate change is an important issue that has sparked fascinating research on its causes, as well as its future effects. There has been significant change in weather patterns and climate over the past century. Sea levels are rising, ice caps are shrinking, and extreme unexpected disasters are occurring all over the world at an alarming rate. This means devastating outcomes for the future of planet earth, along with all of earth’s inhabitants. Earth is home to billions of people, as well as countless species. The despondent truth is that humanity is to blame for global climate change.
The global pattern of atmospheric heating and circulation is the high precipitation in the tropics which is produced by high rates of evaporation and subsequent concentration of water vapor in ascending air masses. Energy from the sun heats up earth but unfortunately it doesn’t distribute it evenly across the surface of the earth. The tropics receive more heat radiation than they produce the arctic or the polar region produce more radiation than they receive. The clouds formed in this way produce the heavy precipitation associated with the tropics. The mechanisms of high precipitation at temperate latitudes is produced when warm, moisture-bearing subtropical air meets cold polar air, which forces condensation of the water vapor in the subtropical air mass. Precipitation is mainly to do with the temperature of the air. Higher the airs temperature the more moisture it can hold, and vice-versa. Since the tropics are warmer the air holds more moisture and won't lose it until it interacts with colder air, which is usually at mountains as cold air is forced up into the hot air by the ...
The planet Earth goes through cycles in every aspect of its environment from temperature, to water levels, to levels of carbon dioxide in the atmosphere. There has always been a limit to the levels of carbon dioxide in the atmosphere. The Earth is like a human body. If a human does not take care of their body through healthy eating and workouts, they become unhealthy and may have health problems. As with Earth, if Earth takes in more heat than it can let out, or vice versa, there will be global climate changes. This begs the question, what could cause these imbalances to happen on Earth?
Climatology is described as the study of the origins and impacts of climate. To understand climatology, one must know the true definition of climate. Climate, simply, is the typical weather of a specific geographical region on earth. Climate can be affected by many factors. Some of these factors consist of: pollution, outgassing of volcanoes, seasonal changes, natural disasters, and carbon dioxide emissions, and greenhouse gasses. Ultimately, these factors lead to a phenomenon called climate change. Pollution, carbon dioxide emissions and the trapping of greenhouse gasses are most known for drastically changing earth's climate over the years. Carbon dioxide alone plays a key role in heating up the atmosphere. It alone combined with other greenhouse
On the basis of the evidence, it is accepted that climate change is occurring and the climate will change even further due to our fossil fuel based economy, the increasing number of people and their increasing wealth. The increase in greenhouse gases has already started having impacts on the climate, natural ecosystems and human societies. It is clear that the average surface temperatures have increased and it will continue to do as more carbon dioxide gets released into the atmosphere. The recent warming is unprecedented in both magnitude and speed. The projected warming for the 21st century will expect to create severe problems for natural ecosystems and human societies. Water resources are already suffering from increases stresses, and are likely to be reduced. This will inhibit the growth of crops and adversely affect other water uses such as water use for industries and the water supply for the human population. This will lead to more severe food shortages. The glaciers and ice sheets are already retreating, and will retreat more which will lead to changes in the total and annual cycle of river flow in some rivers, threatening water supplies further. Impact on the ecosystems will affect the distribution and productivity of plant and animal species and water supply. A loss of biodiversity is likely to be accelerated by climate change. There will be an increase in extreme weather events such as increases in flood magnitude and frequencies, increases in drought intensity, frequency and duration as evaporation rates will be greater. Higher average temperatures and possibly increased variability are likely to lead to increased frequency and severity of heat waves, causing additional deaths due to heat stress and vector-borne disea...
Environmentalist say, evaporates moisture from wet land, leading to more precipitation. An effect of this is it observes what little moisture the dry land produce. Since 1970 global warming temperature has increase about 1.5 degrees Fahrenheit. The warmer the air the more water it contains. U.S. overall prediction from l900’s has increased, however; in the last 35 years, in has increase by 7 percent. Rain has increase up to l4 percent and heavy rainfall has gone up to 20 percent. For example when the news procast announces it will be slight rain in reality it has been seen that it usually the opposite which it end up raining even harder. In the other hand, there are certain areas in the Midwest that are seen an Dry areas which are part of the U.S. mainly located in the Southwest, where it become drier. The reason for this is because the warm air pulls up what little moisture there is in the soil, and your able to see more droughts. (Shnayerson, Michael). Global warming is causing the ocean atmosphere to warm up than usual even though oceans already seem to have stireed tropical hurricanes of great intensity and duration than I the past. If global warming continue; ocean storms will increase dramatically. As a result of warming, the entire eco-system of the North Sea is in a state of "ecological meltdown."
Climatic Conditions Across the Globe 1. a) Climatic Conditions: These are conditions arising in the world as a result of a change of weather, including latitude, altitude, winds and ocean currents. Climatic conditions therefore vary in different countries of the world as well as sometimes within the same country. In addition, countries at opposite ends of the earth can have similar climatic conditions. It just depends on their latitude from the equator, i.e. the Caribbean, South Asia are 10-25 degrees north of the equator.
In order to understand the Earth’s climate system, we must first identify some of the components of it. The cryosphere consists of Polar ice caps, sea ice, ice sheets, and glaciers. The geosphere consists of the land, the hydrosphere consists of the oceans lakes and rivers, the biosphere consists of ecosystems, and the atmosphere consists of air. Each one of these components play a role in Earth’s climate system. For example, the cryosphere and its ice caps, glaciers, and ice sheets are important because they reflect some of the solar radiation away from Earth’s surface. The biosphere plays a major in carbon dioxide concentration through photosynthesis and respiration, which as a result, influences climate change. The vegetation present
Global Warming is a condition caused by greenhouse gases and human activities. The increased concentration of greenhouse gases due to activities such as deforestation and fossil fuel burning is causing the Earth’s atmosphere and oceans to warm up. As a result of this, global warming has some serious effects in the shape of extreme weather, species extinctions, and rising sea levels. These effects can contribute to the changes that are taking place all over the world, most of which are dangerous enough to pose a threat to the survival of life on Earth in the future.
