Urban areas are getting more crowded, and this can affect the air we breathe and how hot it gets. To make cities healthier and more comfortable, a new method has been developed to improve airflow in cities. By evaluating how well air moves through buildings and streets, we can create plans to make cities better for people to live in. This approach focuses on making sure that urban areas are designed with people's health and well-being in mind. By improving ventilation in cities, we can help reduce air pollution and heat stress, making urban living safer and more pleasant for everyone.
