Reduced evaporation curtailed cloud growth, cutting off the supply of rain to much of Australia. Drought was severe. In the 1992 El Nino, the Indian Ocean remained warm and supplied copious moisture for good rains. Something we have learned recently is that each El Nino is very different. This is particularly true for the rainfall in Australia.
Lobsters have an interesting and rather hazardous life cycle.
The little larvae hatch at the edge of the continental shelf in summer. They then drift to the ocean surface and get blown offshore by the southerly winds that prevail at that time and they spend most of the winter out in the open ocean. Every spring, the young lobsters head back to the coast where they grow to a size suitable for the lobster pot. By counting the number of springtime young, the puerilis, the scientists have discovered that when the Leewin Current flowing down the western Australian coast weakens, there are fewer puerilis. Quite why there are fewer puerilis remains a mystery, but El Nino is a suspect.
