The development of local circulations around the Lena River and their effect on tower‐observed energy imbalance
Abstract Horizontal wind speed and vertical wind speed fluctuation data obtained from aircraft during the GEWEX Asian Monsoon Experiment‐Siberia (GAME‐Siberia) project revealed the development of a local circulation in the atmospheric boundary layer (ABL) near the Lena River, Siberia.
