为研究短期气象事件对苏黎世湖浮游植物春季水华的影响，对1983年苏黎世湖浮游植物春季水华的演变进行了研究。水华可分为四个不同的生长期(3月1日至4月28日)和衰退期(4月29日至5月16日)。在四个生长期内，生长脉冲与高太阳辐射、少风和浅混合层有关，而停滞或损失与强风和随之而来的混合层加深有关，导致不利的有效光照气候。种群数量的减少是由浮游动物的捕食造成的，可能再加上营养限制和其他因素。
The development of the phytoplankton spring bloom in Lake Zürich in 1983 was investigated using frequent sampling with short sampling intervals, which allowed the influence of short-term meteorological events on the bloom to be studied. The bloom can be divided into four distinct growth periods (March 1–April 28) and a period of collapse (April 29–May 16). During the four growth periods, growth pulses were found to be associated with high solar radiation, little wind and a shallow mixed layer, whereas stagnation or loss was associated with strong winds and a consequent deepening of the mixed layer, resulting in an unfavourable effective light climate. The population collapse was brought about by zooplankton grazing, possibly coupled with nutrient limitation and other factors.
