When it comes to weather, the United States is a diverse and dynamic country. From the sunny beaches of California to the snowy peaks of Colorado, the weather varies greatly across the nation. In this article, we will delve into the various aspects of weather in the United States, including climate patterns, seasonal changes, and regional differences.
Climate Patterns
The United States is characterized by a variety of climate patterns, which are influenced by its vast size and varied topography. The country can be broadly divided into four main climate zones: tropical, temperate, arctic, and alpine.
