The north sector includes the GLOBE countries of: Bahamas, Costa Rica, Dominican Republic, El Salvador, Guatemala, Honduras, Mexico, and Panama.
In the northern most part of the sector, Mexico and the Caribbean side of Central America recorded slightly warmer than normal temperatures. On the Pacific side of Central America, however, temperatures were below average, possibly associated with La Niña.
The central sector includes the GLOBE countries of: Bolivia, Colombia, Ecuador, Peru, Suriname, and Trinidad and Tobago.
In Colombia and Ecuador especially, temperatures were about +1.0 to +1.5 degrees Celsius above the 1971-2000 average. The other countries in this sector did not experience such strong signals. Suriname was the opposite of Columbia and Ecuador, where temperatures that were about -1.0 to -1.5 degrees Celsius below average were observed.
The south sector includes the GLOBE countries of: Argentina, Chile, Paraguay, and Uruguay.
This sector saw slightly below average temperatures for 2010. Paraguay experienced unusually low temperatures and snowfall from May through August. Some overnight temperatures were as much as 10 degrees Celsius below the average, causing many regions to declare states of emergencies!
In the north sector, 2010 was the second wettest year in Mexico since 1941. Record high precipitation was recorded for the months of February and July. These heavy rains caused mudslides, yet also filled dams that had been depleted due to many years of drought. Tropical cyclone activity and heavy rain associated with them contributed to the large rainfall in Mexico. In 2010, there were 13 named storms in the Caribbean, with seven hurricanes and three major hurricanes. This does not include the tropical depressions, which are not named but can still bring large amounts of rain.
In the central sector, the influence of El Niño and La Niña was apparent. While temperatures in Colombia and Ecuador were above average, so was their precipitation. The other countries observed below average rainfall, with values of 20-40% below average. In January, strong hail and precipitation caused flooding along the Vilnacota River, interrupting railway service and forcing evacuations.
In the south sector, recall temperatures were only slightly below average however, precipitation was significantly below average. Rainfall deficits were about 20-80% of normal. Even with the deficits, the sector experienced extreme precipitation events, which included flooding and snowfall that lead to destruction of bridges and other man-made structures.
