Similar to what occurred during summer 2011, Peru's soy and corn production is under the shadow of La Nina weather as it would negatively alter rainfall and temperature patterns of the region.

In 2011 spring started out cool and wet in Indiana with planting delays occurring during April and May and during summer the region experienced drought conditions and a lot of heat stress were the crops performance came down considerably. The dry weather bias across the Midwest from August through September last year was in part a function of La Niña and it was not solely responsible for the drought in Indiana and Illinois during early summer last year.

However late in summer during August and September La Niña reasserted itself and the drought in Indiana and Illinois spread to other immediately neighbouring states, said Drew Lerner meteorologist and owner World Weather Inc.

According to Lerner Frequent rains from Texas into the Midwest (like we've seen in December) this winter and spring would help reduce the potential for a worst case of La Niña induced dryness this summer and easing the dryness in Texas would also help reduce the potential for a significant high pressure ridge to build up in late spring and summer. "If the prevailing weather pattern is wet La Niña will have a positive impact by taking the excess moisture out of the pattern and provide timely rainfall. However if the prevailing weather pattern is a dry one La Niña's influence will be to take away more moisture and the drier biased pattern will suddenly become too dry raising concern for crops " commented lernerPublished by HT Syndication.
