What is climate variability?
The climate is a measure of weather patterns for a long time and the climate owns are changes, long -term and short -term. Short -term climate changes are regular or occasional changes that occur, and this is called "climate variability". These short -term changes may include floods, drought, temperature changes or oscillating weather patterns such as El Niño or La Niña. In the most general sense, climate variability is considered to be deviations in climate statistics for a long time. Exactly identification and understanding of climate change is important for recognizing and understanding their effect on people.
The term 'climate' is a term used to describe the average mixture of meteorological conditions in the geographical location in the long run. Scientists determine the climate of the geographical location of compilation statistics for a longer period of time, usually several decades or more. Such statistics include the value, dispersion and probability associated with meteorological conditions such as temperature, humidity, precipitation and wind.
kWhen scientists have been studying climate for a long time, they often find inconsistency in the weather compared to the average. For example, the climate that they are normally wet can experience dry spells or even drought due to a change in weather patterns. Although these short -term changes are their own, they do not mean that the climate has changed. Instead, they are simply a deviation from the used climate of the region. Scientists assign the term "climate variability" to identify such anomalies that usually last for less than ten years.
There are many reasons why the climate differs from the norm. One of the most important natural variations in the climate occurs with the circumstances of El Niño-Southern oscilation (ENSO). Enso explain the interaction of the Pacific Ocean with the atmosphere and creating global climatic deviations. Every few years there have been changes in the surface temperature of the ocean and other meteorological elements around the Pacific equator. Cooler temperatures characterizeLa Niña and warmer temperatures are the signature of the El Niño cycle. Different temperatures create changes in tropical precipitation and distribute climate around the world.
Climate change study is important for scientists because of its effect on people. If scientists can identify formulas or recognize the effect on the weather attributed to climate variability, people can usually acclimatize. To illustrate, the scientist placed the observation system in a tropical pacific that allows the prediction of El Niño has been affected for several years before manifesting in the global climate. This information can help calculate the resulting conditions such as intensified storms or drought conditions before Tim.
On the other hand, when scientists do not understand climate variability, people usually suffer. For example, it is assumed that the 30 years of 30 years were caused by the variability of climate associated with warmer ocean temperatures over the Atlantic Ocean and the effects of La Niña in the Pacific Ocean. If these effects were known in advance than a decade later, scientists could warn againstEdge consequences.
