The melt season refers to the period during the summer when snow and ice start to melt due to warmer temperatures. This process can lead to changes in the Earth's surface, such as the formation of rivers and lakes, erosion, and changes in the landscape. The melt season is an important research area for scientists studying climate change, as it provides valuable information on the rate of melting and the impact on the environment. Studying the melt season can help researchers understand how melting ice contributes to sea level rise and the overall effects of global warming on the polar regions.
