Magnetic reconnection at the dayside magnetopause is a crucial facet of solar wind-magnetospheric coupling, as it drives magnetospheric convection and is necessary for magnetic energy storage in the magnetotail. Many fundamental questions about dayside reconnection remain insufficiently answered quantitatively and even qualitatively, such as the location and local efficiency of reconnection for arbitrary solar wind conditions. The situation is complicated compared to simple two-dimensional models because the dayside naturally is usually asymmetric, has significant flow shear due to the solar wind (especially when the interplanetary magnetic field has a northward component), and manifestly has a three-dimensional structure. This talk will summarize recent work on a number of aspects of dayside reconnection, including the properties of asymmetric reconnection with a flow shear, the efficiency of dayside reconnection, and the local properties of reconnection at the dayside. Theoretical predictions for each of these will be compared to two-dimensional local numerical simulations of reconnection and naturally occurring reconnection in self-consistent three-dimensional global magnetospheric magnetohydrodynamic simulations.
