Understanding Mexico’s Winter Season
Mexico’s winter season has begun with a gradual decrease in temperatures, as expected. The country’s mountainous regions, particularly in the north and center, have been experiencing the effects of the first cold fronts of the season.
While temperatures have dropped, no extreme values have been recorded that exceed historical averages. However, weather forecasts suggest that the coming weeks may bring colder weather conditions, with cold events dependent on the interaction between high and low-pressure systems.
The arrival of new arctic and polar air masses could intensify the effects of winter, leading to lower temperatures and more frequent winter events. Climate variability makes it challenging to accurately predict the climate’s evolution in the coming months.
The Origin and Impact of Cold Air Masses
Cold air masses affecting Mexico originate from the polar and subarctic regions of the northern hemisphere. These air masses, characterized by low temperatures and high density, move south due to changes in atmospheric circulation patterns.
The characteristics of an air mass are determined by its area of origin. Those that form over continents are usually drier and colder than those over oceans. In Mexico’s case, Canada and Alaska have the most significant impact on winter temperatures.
The interaction between cold air masses and the warm, humid air of the Gulf of Mexico can generate various weather phenomena, such as cold fronts, snowfall, frost, and strong winds. These events can cause problems, including power outages, damage to agriculture, and health risks.
Health and Economic Impacts of Low Temperatures
Extreme cold can exacerbate respiratory diseases, such as asthma, bronchitis, and pneumonia. Prolonged exposure to cold, dry air can irritate the respiratory tract and increase the risk of infections. Low temperatures can also increase blood pressure and the risk of heart attacks.
In addition, the physical effort required to keep warm can overload the heart. When body temperature drops below 35°C, hypothermia can occur and be fatal if not treated promptly. Symptoms include chills, confusion, drowsiness, and loss of coordination.
On the economic side, frost and snowfall can damage crops and reduce agricultural production, leading to increased food prices. The drop in temperature can also damage infrastructure, including roads, bridges, and energy systems.
Preparing for Extreme Winter Conditions
Long-range forecasts indicate that the 2023-2024 winter season could be colder than normal in some regions of Mexico, particularly in the north and center. States such as Chihuahua, Durango, Coahuila, and Zacatecas are expected to experience the lowest temperatures.
The National Meteorological Service has warned of the arrival of a considerable number of cold fronts during the coming months. These cold fronts, combined with the country’s topographic conditions, can generate intense snowfall in the mountains of Chihuahua, Durango, and Coahuila.
It is essential for the population to prepare for low temperatures and winter events. Having warm clothing, non-perishable food, and a first aid kit on hand is recommended. Additionally, paying attention to notices and alerts issued by Civil Protection authorities is crucial.
