Monthly Rainfall Summary for December 2016
Rainfall summaries are prepared by the Climate Section of the National Meteorological Service of Belize. The meteorological service maintains a network of over 25 rainfall stations that are situated across the country mainly in the agricultural areas. Rainfall is read at 9:00am each morning and this represents the rainfall for the previous 24 hours.
The rainfall summary for December 2016 shows that with the exception of stations situated in the central western portions of the country (Western Cayo District) most stations recorded above their average rainfall for the month. The main reason why rainfall totals were high was that no cold front crossed the country. Typically when a strong front crosses it brings in dry cold air in its wake. Instead a more tropical pattern dominated throughout the month. The first rainfall event occured between the 10 and 15th of the month when a low pressure system crossing southern Central America induced an inverted trof over the area. The second event was caused by divergent conditions aloft between a ridge east of the area and upper lev trof/low to the west. The resulting upper lev diffluent/split flow supported deep convective activitiy and heavy rainfall over the area especially on the morning of the 26th of December. The maps below show the total rainfall recorded at some key stations and how that total compares to the normal for the month of December. A similar comparison is shown by the bar graph that compares the recorded total for December 2016 againt the climatological norm for the month of December.
The next rainfall summary will be out before the middle of February 2017.
