Review long-term atmospheric patterns and monthly climate averages at a representative coordinate.
Analyze the twelve-month climate cycle of Majuro, Marshall Islands, using representative NASA POWER measurements recorded between 1991 and 2020. Examine monthly trends for mean, minimum, and maximum temperatures alongside average daily precipitation, relative humidity, wind speed, and daylight hours. These data points provide a structured view of local climate normals rather than current weather conditions or short-term forecasts.
