We used newly available quality controlled Enhanced National Climate Services rainfall and temperature products as well as global climate products to investigate likely impacts of climate on malaria evaluations and test the assumption that changing the baseline period can significantly impact on the influence of climate in the assessment of interventions. In four countries Rwanda, Malawi, Mozambique, and Angola there was no strong difference in climate suitability for malaria in the pre- and post-intervention period. In part, this may be due to data quality and analysis issues.

Although almost anything can happen with the weather, climate is more predictable. Climate then is the long-term average of weather. Good climate is why we choose to vacation in Hawaii in February, even though the weather is not guaranteed to be good! Climate is the average of weather in that location over a long period of time, usually for at least 30 years. Climate can change, but only over long periods of time.

Temperature Variability over Africa

Although almost anything can happen with the weather, climate is more predictable. Climate then is the long-term average of weather. Good climate is why we choose to vacation in Hawaii in February, even though the weather is not guaranteed to be good!

Climate is the average of weather in that location over a long period of time, usually for at least 30 years. Climate can change, but only over long periods of time. The climate of a region depends on its position relative to many things. These factors are described in the next sections.

The main factor influencing the climate of a region is latitude because different latitudes receive different amounts of solar radiation. The position of a region relative to the circulation cells and wind belts has a great effect on its climate. In an area where the air is mostly rising or sinking, there is not much wind. The air rises so that it cools and condenses to create clouds and rain.

Climate along the ITCZ is therefore warm and wet. Early mariners called this region the doldrums because their ships were often unable to sail because there were no steady winds. The ITCZ migrates slightly with the season.

Land areas heat more quickly than the oceans. Because there are more land areas in the Northern Hemisphere, the ITCZ is influenced by the heating effect of the land. In Northern Hemisphere summer, it is approximately 5o north of the equator while in the winter it shifts back and is approximately at the equator.

As the ITCZ shifts, the major wind belts also shift slightly north in summer and south in winter, which causes the wet and dry seasons in this area. At about 30 degrees N and 30 degrees S, the air is fairly warm and dry because much of it came from the equator where it lost most of its moisture at the ITCZ.

At this location the air is descending, and sinking air warms and causes evaporation. Mariners named this region the horse latitudes. Sailing ships were sometimes delayed for so long by the lack of wind that they would run out of water and food for their livestock. Sailors tossed horses and other animals over the side after they died. The prevailing winds are the bases of the Hadley, Ferrell, and Polar Cells. These winds greatly influence the climate of a region because they bring the weather from the locations they come from.

For example, in California, the predominant winds are the westerlies blowing in from the Pacific Ocean, which bring in relatively cool air in summer and relatively warm air in winter. Local winds also influence local climate. For example, land breezes and sea breezes moderate coastal temperatures. The temperature of the water offshore influences the temperature of a coastal location, particularly if the winds come off the sea. The cool waters of along the western United States is caused by a clockwise rotating ocean current that is bringing cold water from the arctic toward the equator.

The climatic effect is that coastal regions of California, Oregon, and Washington are are cool. Coastal upwelling also brings cold, deep water up to the ocean surface off of California, which contributes to the cool coastal temperatures. But that same ocean current brings warm, tropical water to eastern Japan. In the Atlantic Ocean, the northern ocean current, called the Gulf Stream , brings warm water from the tropics to the southern states. This is a major reason why the southern states experience humid conditions in the summer and tornadoes because of all this warm moisture.

The Gulf Stream also impacts Europe by bringing warm water northward, making this region that is rather northward warmer than expected. Air pressure and air temperature decreases with altitude. The closer molecules are packed together, the more likely they are to collide. Collisions between molecules give off heat, which warms the air. At higher altitudes, the air is less dense and air molecules are more spread out and less likely to collide.

A location in the mountains has lower average temperatures than one at the base of the mountains. In Colorado, for example, Lakewood 5, feet average annual temperature is 62 degrees F 17 degrees C , while Climax Lake 11, feet is 42 degrees F 5. Mountain ranges have two effects on the climate of the surrounding region. The second effect mountains have on climate systems is the ability to separate coastal regions from the rest of the continent.

Since a maritime air mass may have trouble rising over a mountain range, the coastal area will have a maritime climate but the inland area on the leeward side will have a continental climate.

Latitude The main factor influencing the climate of a region is latitude because different latitudes receive different amounts of solar radiation. Days are equally long year-round and the sun is just about directly overhead at midday. The polar regions receive the least solar radiation.

The night lasts six months during the winter. Even in summer, the sun never rises very high in the sky. Sunlight filters through a thick wedge of atmosphere, making the sunlight much less intense. Licenses and Attributions. CC licensed content, Shared previously.

What Are the Different Climate Types?

It is the hottest place in China, if not the world, or so says the local lore. According to local lore, the Flaming Mountain is the hottest spot in China. After visiting the site, scientists used NASA data to find out for sure. And that got Running thinking: exactly where is the hottest place on Earth? Think dry, rocky, and dark-colored lands. But just nine years later, on September 13, , a weather station in El Azizia, Libya, recorded a temperature of The reason is partly about where the measurements are made.

Pattern and Trend of Night Land Surface Temperature in Africa

Climate is the average weather conditions in a place over a long period of time—30 years or more. And as you probably already know, there are lots of different types of climates on Earth. For example, hot regions are normally closest to the equator. The snow-covered peaks of the Chigmit Range during winter.

How the Temperature Varies During the Day and Night

Introduction

The Intergovernmental Panel on Climate Change IPCC Fourth Assessment Report AR4 Pachauri and Reisinger considered that progress in understanding of how climate is changing in space and in time has been gained through improvements and extensions of numerous datasets and data analyses, broader geographical coverage, better understanding of uncertainties, and a wider variety of measurements. However, data coverage remains limited in some regions. The AR4 report shows, through the use of station data, that the warming of the climate system is unequivocal, with 11 of the last 12 years — ranking among the 11 warmest years in the instrumental record of global surface temperatures since Trenberth et al. The report also notes that the total temperature increase from the period —99 to the period —05 is 0. The main conclusion of AR4 is that most of the observed increase in globally averaged temperatures since the midtwentieth century is very likely due to the observed increase in anthropogenic greenhouse gas emissions Hegerl et al.

Джабба взял в руки распечатку. Фонтейн молча стоял. Сьюзан заглянула в распечатку через плечо Джаббы. - Выходит, нас атакует всего лишь первый набросок червя Танкадо. - Набросок или отшлифованный до блеска экземпляр, - проворчал Джабба, - но он дал нам под зад коленом.
