Monthly Weather Summary, February 2022National Meteorological Service of Belize
February is typically the second most active month for frontal systems during the dry season which is one of the sources of rainfall. On average, a total of eight cold fronts, one stationary fronts, two upper-level troughs and one surface trough would influence weather conditions and rainfall in February, a total of two cold fronts, two stationary front, one surface trough and ten high pressure systems affected the country. Overall, rainfall was above normal over most areas, except for south-eastern Belize which received near normal due to rainfall activity from the passage of the fronts and fronts that dissipated and stalled over the area.
The first week started off relatively dry over the country through to February 4. This was due to a very dry airmass over the area with riding in both the lower and upper levels. This resulted in subsidence inhibiting any significant rainfall development as a neutral to convergent upper-level pattern prevailed. Upper-level winds were mostly zonal while near the surface, a moderate east to south-easterly flow prevailed. Skies were clear to partly cloudy during this period with little to no rainfall, except for isolated showers around the country and isolated thunderstorms over the Maya Mountains in the afternoon and evening on February 4 as a cold front approached the country and the low-level winds became north-easterly with moisture advection unto the mainland from over the northwest Caribbean. On February 5, a cold front extended from the western North Atlantic to the Yucatan Peninsula resulting in an increase in low level moisture while the upper levels continued very dry. A neutral to weakly divergent upper-level flow prevailed and supported an increase in showery activity and isolated thunderstorms around the country but mostly over central and offshore areas. The north-easterly flow behind the front supported rain over northern areas overnight on the 6 and offshore areas during the day with fair weather to end the week the 7th.
The front became stationary over the western Yucatan and moist conditions prevailed in the low levels for the remainder of the week. This was accompanied by a light to moderate north to north-easterly surface flow through to the 11th in neutral to weakly divergent conditions from a digging upper-level trough with a west to south-westerly flow. Showers were isolated on February 8th then a few showers affected central and offshore areas on February 9th. Between February 10th and 11th, no significant activity occurred on the mainland with only light rain concentrated over offshore areas. Another cold front was approaching the area on February 12th and was located over the North-western Gulf of Mexico with a deep polar trough to the west of the country supporting a few showers over northern and central locations during the morning hours. The cold front crossed the country on February 13th and extended to central Belize with showers being isolated at first, increasing and affecting the north in the afternoon, then some showers, periods of rain and isolated thunderstorms affected central and southern locations. The front became stationary near Nicaragua on the 14th and supported a windy, cool north-westerly flow as a strong ridge build over the area behind the front. Moisture levels continued very high over the area, but rainfall activity was mostly over offshore areas,
Cool temperatures prevailed into week three from the passage of the cold front with relatively moist conditions continuing in the low levels up to February 17th. Showers and light rain persisted mainly along coastal areas on the 15th, then over northern and inland locations as conditions continued neutral to weakly divergent over the country due to troughing supporting a south-westerly upper-level flow. A tight pressure gradient supported a moderate east to south-easterly flow. Conditions became drier over the area on February 18th to 21st with a high-pressure ridge supporting a moderate east to north-easterly flow and neutral to weakly convergent upper-level pattern with a broad upper-level ridge over the southwest Caribbean. This yielded a west to south-westerly flow aloft through to the end of the week. During the period, showers were isolated, except for a few more over some northern and southern locations periodically.
During the last week of the month, the main feature affecting the weather both at the lower and upper level was a ridge pattern. This supported dry conditions across the country with mostly an east to south-easterly flow in the low levels, and a south to south-westerly flow at the upper levels with a neutral to weakly divergent pattern. Showery activities were predominantly isolated, with slightly more occurring over some central and southern locations.
The graph and maps below summarize the total rainfall and average maximum and minimum temperatures. They also give an indication of how these readings compare to the normal for the month across the stations sampled. As can be seen, most of the country experienced above normal rainfall. In terms of temperatures, most of the stations sampled show near normal maximum/daytime except for Melinda in the south that was slightly above normal and slight above normal minimum/night-time temperatures.
