Researchers studied heat flux over a mire in the Sanjiang Plain to understand how wetland ecosystems interact with their environment. By observing heat exchange between the wetland and the air from June to October 2004, they found that heat flux varied greatly during the day and seasonally. The amount of heat transferred as vapor decreased from June to October, while heat transferred as temperature remained mostly constant. Heat exchange peaked around noon and was influenced by factors like sunlight and vapor in the air. Vapor affected heat exchange more in daylight hours, while temperature was the main influence overall. This research helps us understand how wetlands and the atmosphere interact during different times of the day and year.
