Monsoon Climate Variabilities
نویسنده
چکیده
The Asian monsoon consists of three subcomponents, Indian monsoon (IM), East Asian monsoon (EAM), and western North Pacific monsoon (WNPM). All these submonsoon systems exhibit remarkable intraseasonal and interannual variabilities. In this chapter, we will review recent progress in understanding the monsoon annual cycle and some of major issues related to the monsoon intraseasonal and interannual variabilities; describe the spatial-temporal structure of the northward propagating intraseasonal oscillation in the monsoon region; and discuss what physical processes lead to quasi-biennial and lower-frequency variabilities of the India monsoon, how El Niño (La Niña) events have a delayed impact on East Asian climate, and how the atmosphere-ocean interaction in the monsoon–warm ocean leads to the tropospheric biennial oscillation. Specific emphases are placed on the discussion of the physical processes that are responsible for the described phenomena.

A signi cant portion of the world's population is under the in uence of monsoon changes. Understanding of physical processes governing the evolution of Asian monsoon is not only important for regional climate variation, but also crucial to global climate variation. Besides bringing rain to land, monsoons also change ocean currents, ocean upwelling, and coastal ecology. Over land the consequence...

متن کاملInfluence of the solar activity on the Indian Monsoon rainfall
We use 130 years data for studying correlative effects due to solar cycle and activity phenomena on the occurrence of the Indian Monsoon rainfall. We compute the correlation coefficients and significance of correlation coefficients for the seasonal and the annual data. We find that: (i) for the whole years 1871–2000, the spring and southwest monsoon rainfall variabilities have significant posit...

The western Pacific Ocean plays an important role in regulating and modulating the global climate system on interannual to geological timescales. Excellent records have been acquired by coring high sedimentation rate sites in the marginal seas of the western Pacific Ocean during IMAGES cruises. This special section has been proposed to publish papers presenting high-resolution records and the i...

1. Introduction In dry desert regions like the Southwest U.S., natural and human systems are particularly sensitive to variations in climate. The natural ecosystem of the Sonoran Desert is largely dependent on and adapted to monsoon precipitation, which is also needed to maintain water demand and agriculture from year to year. From a resource management perspective, the monsoon is relevant in t...
