The two most important factors in the climate of an area are temperature and precipitation. The yearly average temperature of the area is obviously important, but the yearly range in temperature is also important. Some areas have a much larger range between highest and lowest temperature than other areas.

Climate features also include windiness, humidity, cloud cover, atmospheric pressure, and fogginess. Latitude plays a huge factor in determining climate. Landscape can also help define regional climate. A region’s elevation, proximity to the ocean or freshwater, and land-use patterns can all impact climate.

When scientists focus on climate from before the past 100-150 years, they use records from physical, chemical and biological materials preserved within the geologic record. Organisms (such as diatoms, forams and coral) can serve as useful climate proxies. Other proxies include ice cores, tree rings, and sediment cores.

: a long narrow meandering current of high-speed winds near the tropopause blowing from a generally westerly direction and often exceeding a speed of 250 miles (402 kilometers) per hour.

A low-pressure system usually brings cool dry air and clear skies, while a high-pressure system brings clouds and precipitation. A low-pressure system usually brings clouds and precipitation, while a high-pressure system brings cool dry air and clear skies.

Which best explains how El Niño affects the jet stream? The jet stream is pushed north and results in increased precipitation. The jet stream is pushed south and results in increased precipitation.

Which best describes a characteristics of the jet stream? It forms a boundary between a cold air mass and a warm air mass. The weather forecast indicates that a warm front will be moving into the area in the next 24 hours.

Depending on their characteristics and height in the atmosphere, clouds can influence the energy balance in different ways. Clouds can block a significant portion of the Sun’s incoming radiation from reaching the Earth’s surface, as anyone who has had a day at the beach inter- rupted by heavy clouds can tell you.

Which statement best describes a bacterial cell? it is a complete organism, preforms all life functions. Which characteristic do single-celled organisms and multi-cellular organisms have in common? both have a way to get rid of waste material.

There are four common forms of bacteria-coccus,bacillus,spirillum and vibrio.

Examples include Listeria monocytogenes, Pesudomonas maltophilia, Thiobacillus novellus, Staphylococcus aureus, Streptococcus pyrogenes, Streptococcus pneumoniae, Escherichia coli, and Clostridium kluyveri.
