Comparisons of neutral wind velocities with and without JRA-55. The eastward neutral wind velocities at 120 km with and without JRA-55 for five different periods in Okinawa 2019 are compared, starting from the same initial values at 0 UT of the first day of the 5 months in 2019: a July, b August, c September, d October, and e November. The black line and the red line indicate neutral wind velocities with and without JRA-55, respectively
