JASMINE: The Joint Air-Sea Monsoon Interaction Experiment: A Pilot Study of Ocean-Atmosphere Interaction During Active and Break Phases of the Summer Monsoon

拟议的实验是一项为期两年的合作研究，目的是研究海气通量、海气相互作用、对流和上层海洋对夏季风在活跃和间歇(间歇期)之间振荡时的变化的响应。作为一项试点研究，海气季风相互作用联合实验(茉莉花)将对孟加拉湾地区进行海洋和气象调查。海气通量、大气状态和大气内对流将在一个被观察到是夏季季风季节内变化中心的区域确定。茉莉花是华盛顿大学、夏威夷大学和科罗拉多大学的合作项目。合作的这一部分将研究对流的形式及其在季节内和大尺度变化中的作用。将讨论对流-大尺度相互作用的作用、季风系统对对流反应的活跃和中断阶段、印度洋对流的可预测性以及日循环在调节印度洋对流活动中的作用等科学问题。这项研究很重要，因为收集和随后分析一套全面的数据将对季风间歇期和活跃期的海-气相互作用产生深刻的见解。准确预测季风爆发和季风降雨量是一项科学挑战，也具有巨大的经济后果。

The proposed experiment is a collaborative two-year study of the air-sea fluxes, air-sea interaction, convection and the upper ocean response to the variations of the summer monsoon as it oscillates between active and the lulls in between (break periods). A pilot study, the joint air-sea monsoon interaction experiment (JASMINE) will conduct an oceanographic and meteorological survey of the Bay of Bengal region. Air-sea fluxes, the state of the atmosphere and convection within the atmosphere will be determined in a region that has been observed to be a centroid of intraseasonal variability in the summer monsoon. JASMINE is a collaborative project of the University of Washington, University of Hawaii, and the University of Colorado.This component of the collaboration will examine the form of convection and its role in the intraseasonal and large scale variability. Scientific questions regarding the role of convective-large-scale interaction, active and break phases of the monsoon system responses to convection, predictability of convection over the Indian Ocean, and role of diurnal cycle in modulating convection activity in the Indian Ocean, will be addressed. The study is important since gathering and subsequent analysis of a comprehensive set of data, will yield insights into the air-sea interactions during break and active periods of the monsoon. The accurate prediction of monsoon onset and monsoon rainfall is a scientific challenge that also has enormous economic consequences.
