Summary
The article provides an in-depth analysis of the coldest cities in the United States, detailing the criteria for ranking and the effects of geographical factors such as elevation, proximity to bodies of water, and latitude. These rankings rely on long-term temperature averages collected over several decades for the U.S National Centers for Environmental Information, factoring in areas with over one million residents as per 2020 U.S Census Bureau data. Special attention is also given to cities with at least 10,000 residents, using data obtained from World Population Review and Climate Data Online. The article not only identifies these frigid locations but also delves into the impact of cold weather on cultural practices, infrastructure adaptations to extreme weather, and geographical factors contributing to extreme cold temperatures. This comprehensive exploration underscores the importance of understanding city temperatures for both scientific and human comfort purposes.
Criteria for Determining the Coldest Cities in America
The identification of the coldest cities in the United States relies on long-term temperature averages. These averages are based on weather data collected over several decades, for instance, from 1991 to 2020, for the US National Centers for Environmental Information . This data is used to rank the metropolitan areas with the most residents, all with over one million residents in 2020, as per the US Census Bureau .
Studies have been conducted that compile lists of the coldest cities based on data obtained from World Population Review. This review considers the lowest minimum average temperatures in cities with at least 10,000 residents . In the case of a tie, additional data obtained from Climate Data Online, showing the lowest recorded temperatures for each city, is used to break the tie .
The coldest city in each state, determined by average temperature, is also often considered . Moreover, the temperatures of these cities are compared with the global average temperature, which has been rising, leading to widespread changes in weather patterns .
The determination of city temperatures is not only fascinating but also scientifically important, particularly from the perspective of human discomfort . Estimations of city temperatures are also made based on data regarding city geography . For example, annual mean temperature is given by the average temperature of the maxima and minima for the warmest and coldest months, primarily varying with latitude, although the influence of warm and cold ocean currents is also identified .
Temperature can vary for several reasons such as shade, sun, nearby buildings (or lack of them), and inversions, which is the phenomenon of colder air sinking into valleys because it’s heavier than warm air . Cities with moderate temperatures all year round tend to rank high in terms of livability .
Impact of Geographical Location on Temperatures
Temperatures in different cities can vary significantly due to several geographical factors, affecting both the hot and cold extremes. These factors include the city’s elevation, proximity to bodies of water, and latitude, all of which contribute to the city’s overall climate.
Elevation
As height above sea level increases, temperature decreases. For every 100-meter increase in elevation, the average temperature decreases by about 0.7°C. This is due to the thinning of the atmosphere with altitude, which allows more heat to escape.
Proximity to Bodies of Water
Cities located near bodies of water such as oceans, lakes, and rivers often experience more moderate temperatures than those that are further inland. This is because water takes longer to heat or cool, causing it to moderate the temperatures of the air around it . During the night, rocks, soil, and buildings lose their heat faster than bodies of water, resulting in smaller fluctuations in temperature.
Latitude and Ocean Currents
Latitude also plays a significant role in a city’s temperature. Places at lower latitudes can still be cool if they are at high elevations or near cold ocean currents. Ocean currents transport warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics, helping to counteract the uneven distribution of solar radiation reaching Earth’s surface.
Analysis of Specific Coldest Cities
Fairbanks, Alaska
Fairbanks, Alaska, situated in or near the boreal moist forest biome, is one of the coldest cities in the U.S.. Factors contributing to Fairbanks’ cold temperatures include its latitude and elevation. Changes in altitude and moisture patterns can also lead to variations in local climates, impacting plant and animal life and influencing the formation of storms.
Influence of Water Bodies
Water bodies significantly influence the climates of nearby areas. This results in fewer temperature extremes in locations near water bodies, with these areas typically not becoming as hot or as cold as locations further inland.
Effects of Climate Change
Climate change has been linked to more extreme temperature conditions. Rising global average temperatures are associated with widespread changes in weather patterns, with scientific studies indicating that extreme weather events such as heat waves and large storms are likely to become more frequent or intense with human-induced climate change.
Other Notably Cold Cities
Other notably cold cities in the U.S. include Grand Forks, ND, which is recognized as the coldest city in the contiguous United States. These ratings are based on long-term temperature averages from weather data collected from 1991 to 2020 for the U.S. National Centers for Environmental Information. The coldest cities are typically those that experience consistently cold temperatures, determined by evaluating cities’ mean annual temperatures over a 30-year period.
Influence of Cold Weather on Cultural Practices and Traditions
The climate of a city significantly affects the lifestyles, cultural practices, and outdoor activities of its residents. For example, in Savannah, where winters are mild, popular activities include riverboat cruises, walking tours, and exploring historic neighborhoods . Conversely, in Fairbanks, Alaska, where extreme cold is a way of life, the local culture and traditions have adapted to these harsh conditions .
Increasingly, extreme temperature conditions are becoming more commonplace across the United States . This development also offers opportunities for cultural growth and evolution as residents adapt their lifestyle and traditions to meet the changing climate. This trend is particularly noticeable in high-altitude regions, considered climate “hotspots” that anticipate or amplify climate change impacts occurring at lower altitudes .
Moreover, cold weather climates can foster unique aspects of local cultures. For instance, Boston, despite experiencing snowy winters, remains a walkable city, while Minneapolis, notorious for its cold weather, has developed a robust bicycle infrastructure around its many lakes . These adaptations reflect a cultural response to climatic conditions and significantly influence the social and outdoor practices of the cities’ residents .
Evolution of Local Infrastructure to Combat Extreme Weather
The progression of local infrastructure to counteract extreme weather varies across cities, especially in colder areas. Topographical factors, including proximity to bodies of water, contribute significantly to the climatic conditions of a city, subsequently influencing infrastructure development. In certain circumstances, climatic conditions can have direct consequences on infrastructure, as evidenced in Texas in 2021 where cold temperatures resulted in significant power outages and water service disruption due to the exposure of pipes and equipment to the air.
The adaptation of local infrastructure to climate challenges necessitates considerable financial investment, much of which is facilitated by the federal government. Local governments primarily rely on the municipal bond market for infrastructure project financing, with support from federal tax incentives. The federal government also provides indirect infrastructure support through financing mechanisms or tax incentives, such as the Transportation Infrastructure Finance and Innovation Act (TIFIA) of 1998. This act offers low-interest loans and other credit assistance for local governments to finance their infrastructure projects.
Geographic Factors Contributing to Extreme Cold Temperatures
Geographic factors, such as proximity to large bodies of water, altitude, and topography, significantly contribute to the extreme cold temperatures experienced in some of the coldest cities in the United States.
Proximity to Water Bodies
Being close to a significant body of water, such as Lake Superior, can result in what is known as the “lake effect snow,” leading to extremely cold weather conditions.
Altitude
The temperature usually decreases as the elevation or height increases, making locations at higher elevations colder. This can be particularly impactful in cities situated in or near mountain ranges, which are considered climate “hotspots” due to their distinct perspective on climate change and extreme weather.
Topographical Influence
Topographical features also significantly influence a city’s climate. For example, downslope winds can cause chilly nights in valleys, while the “heat island” effect can elevate nighttime temperatures in cities.
These geographic factors, combined with long-term temperature averages, are considered in the ratings of the coldest cities in the United States.
Effect of Elevation on Cold Temperatures in the Coldest Cities
Air temperature in various locations is greatly influenced by their elevation. As a general rule, with every increase in height by 100 meters, the average temperature tends to decrease by 0.7°C. This factor, therefore, plays a significant role in the temperatures experienced in the cities considered to be the coldest in America.
These cities are normally expected to not reach a temperature of zero degrees Fahrenheit, which goes to show the major role played by elevation in these low temperatures.
