印度夏季风（ISM）爆发通常发生于2024年5月末到6月初，标志着印度雨季的来临，具有很强的年际变率。ISM爆发的早晚对印度农业播种时间和夏季气候有重要影响。因此，许多研究者致力于寻找ISM爆发的影响因子，以提升对它的预测。以往的研究主要侧重于揭示影响ISM爆发的热带系统，例如厄尔尼诺-南方涛动、热带季节内振荡等。

A mass balance inverse modelling procedure is applied with a time-dependent methane concentration boundary condition and a chemical transport model to relate observed changes in the surface distributi...
1990s长江流域降水趋势分析
长江流域 降水 趋势分析 1990s
2008/12/2
依据国家气象局提供的实测月降水和日降水资料，运用Mann-Kendall (M-K)非参数检验法验证了降水趋势，并通过空间插补法，由点扩展到面，分析了1990s长江流域降水变化特征，发现1990s长江流域降水变化以降水在时间和空间分布上的集中度的增加为主要特点：时间上，年降水的增加趋势以冬季1月和夏季6月降水的集中增加为主；一日降水量大于等于50mm的暴雨日数和暴雨量在1990s也有了较明显的增加...
Can we reconcile differences in estimates of carbon fluxes from land-use change and forestry for the 1990s
carbon fluxes land-use change forestry
2008/11/11
The effect of Land Use Change and Forestry (LUCF) on terrestrial carbon fluxes can be regarded as a carbon credit or debit under the UNFCCC, but scientific uncertainty in the estimates for LUCF remain...
