Lethal gas releases from Lakes Nyos and Monoun in Cameroon seem to be more lacustrine than volcanic in origin. Both of these events occurred in August and were only 2 years apart. Data show that the period of deepest mixing and lake turnover also occurs during late summer in this region of tropical Africa. In addition, recent trends of decreases in both air temperatures and effective insolation relative to long-term means suggest that weakening of stratification, coupled with a predictable seasonal interval of reduced stability in August, may be responsible for the timing of these events.
喀麦隆尼奥斯湖和莫农湖致命气体的释放似乎更多地是源于湖泊，而不是火山。这两起事件都发生在 8 月，相隔仅 2 年。数据表明，在非洲热带地区的这个地区，深层混合和湖泊翻转的时期也发生在夏末。此外，与长期平均值相比，空气温度和有效太阳辐射最近呈下降趋势，这表明分层减弱，加上 8 月稳定度降低的可预测季节性间隔，可能是导致这些事件发生的原因。
