Because wind chill temperature is not an exact science, weather services in different countries use standards relevant to their particular region, and thus its estimates may differ from those provided by local weather services in other regions. The perception of lower temperatures caused by wind led to the development of many different formulas that attempt to qualitatively predict the effect of wind on this perceived temperature. The physiological response of the body to an increased rate of heat loss is the generation of more heat to maintain surface temperature, resulting in the perception of lower temperatures due to greater heat loss. The result of wind chill is to increase the rate at which heat loss occurs. The faster the wind speed, and thus the movement of the surrounding air, the faster the surface cools. Essentially, as the air around a body moves, it disrupts the warm air surrounding the body, allowing cooler air to replace the warm air. Convection is defined as heat transfer due to the bulk movement of molecules within fluids such as gases and liquids, such as wind. Although conduction and radiation are relevant to heat transfer, wind chill temperature is mostly a result of convection. Refer to the Heat Index Calculator for further detail.Ī surface, such as the skin on a person's body, loses heat through conduction, convection, and radiation. This is similar to the body feeling a higher temperature under high humidity conditions in the summer. In winter, the temperature felt by the body is typically lower than the actual air temperature.

Provides assistance to low-income households in meeting their immediate home energy needs. NYS Low Income Energy Assistance Program (LIHEAP) Resources for Families for Heating Assistance Provides updated guidance on preparation, modifications, and monitoring for safe participation in outdoor sports/physical activities in warm to hot climatic conditions. Revised recommendations on prevention, recognition, and treatment of exertional heat illnesses including exercise-associated muscle cramps, heat syncope, heat exhaustion, and exertional heatstroke.Ĭlimatic Heat Stress and Exercising Children and Adolescents National Athletic Trainers’ Association Position Statement on Exertional Heat Illnesses Lightning Safety Tips National Weather ServicesĬontains safety info for groups/venues, model lightning safety plans, and resources for educators Includes resources for heat and cold on heat index and guidelines, wind chill procedures, early season acclimatization, and thunder and lightning. New York State Public High School Athletic Association (NYSPHSAA) Web-based training on heat-related illness to promote the development and implementation of guidelines including an emergency plan by coaches, athletic trainers, students, school nurses, parents, and teachers. Recognizing, Preventing, and Treating Heat-Related Illness serves as the premier source of heat and health information to reduce the health, economic, and infrastructural impacts of extreme heat by providing planning, education, and action tools. National Integrated Health Information System National Oceanic and Atmospheric Administration (NOAA) provides information on the health dangers of heat, how to prepare, the danger of leaving children in cars, and additional information from the American Red Cross. The OSHA Health Illness Prevention campaign educates employers and workers on the dangers of working in the heat. Provides an overview of heatstroke, heat exhaustion, heat cramps, and heat rash with prevention strategies for children and athletes.
