positive temperature anomaly meaning in English

正温度异常
正向温度异常

If a decadal positive temperature anomaly occurs in the eastern tropical pacific , the atmospheric response excites a anticyclonic wind stress anomaly in the east of australia , which will lead to generate a negative temperature anomaly in the western tropical south pacific
当热带东太平洋的海温为暖异常，它将激发澳大利亚的东部沿岸的大气产生反气旋性风应力异常，在这种风场的作用，下方海水向四周辐散，导致热带西南太平洋的温跃层变浅，产生负的温度异常。
The negative temperature sign can move to the mid tropical pacific then propagates eastward the eastern tropical pacific and change the original positive temperature anomaly . a similar evolution but with an opposite sign follows subsequently . the whole cycle for the enso decadal variability needs about 14 years
负的海温异常可向北传输到热带西太平洋和热带中太平洋，然后东传到热带东太平洋，使其原有的暖异常海温被负的海温异常取代，然后再进行反位相的循环，整个循环过程所需的时间约为14年。
