The Volcanic Signal in Global Climate

进行了几项相关的研究任务，以提高 了解火山爆发对气候的影响。 这些 影响是很重要的，以了解自己的权利， 在估计过去气候变化的数量方面也至关重要， 是由于温室气体的排放，以预测未来 这些气体的影响。 PI将分析过去的气候和火山记录， 以探测过去火山爆发的影响。 这 将涉及创建一个改进的火山指数 适合气候影响。 地表温度的变化 将分析过去140年的季节性变化， 和火山喷发的纬度信号。 此外该 最近一次大气环流模式（GCM）实验的结果 将进行分析，以确定模拟的影响， 火山爆发 20世纪80年代的气溶胶数据集将是 为将来在GCM模拟中使用而创建， ENSO和1982年EL Chichon爆发的相对影响， 80年代的气候变化。

Several related research tasks are undertaken to improve knowledge of the effects of volcanic eruptions on climate. These effects are important to understand in their own right, and are also crucial in estimating the amount of past climate change that was due to greenhouse gases in order to predict the future impact of these gases. The PI will analyze the past climatic and volcanic record in order to detect the effects of past volcanic eruptions. This will involve the creation of an improved volcanic index appropriate for climatic impact. The surface temperature changes of the past 140 years will be analyzed to determine the seasonal and latitudinal signal of volcanic eruptions. In addition, the output from a recent general circulation model (GCM) experiment will be analyzed to determine the impact of the simulated volcanic eruptions. An aerosol data set for the 1980's will be created for future use in GCM simulations to investigate the relative effects of ENSO and the EL Chichon eruption of 1982 for the climate change of the 1980's.
