“…For all the seasons, only one simulation was done using an average diurnal heating rate for different heat sources. As discussed above for the present simplified simulation, only migrating modes (1, 1, 1), (1, 1, −2), (1 ,1, −4), (1, 1, −6), (1, 1, −1), (1, 1, −3), (1, 1, 3) and (1, 1, 2) were used for water vapour heating rates taken from Groves (1982a). For planetary boundary layer (PBL) heating, westward and eastward travelling non-migrating modes (1, 5, 5), (1, 5, 6), (1, 5, 7), (1,5,8), (1,5,10), (1,5,16), (1, −3, 3) (1, −3, 4) and (1, −3, 5) were used.…”
