According to the study [42], a = Köppen–Geiger’s climate classification (A = tropical; C = subtropical; w = water deficiency in winter; a = hot summer) and b = Thornthwaite’s climate classification (C1 = dry subhumid; C2 = subhumid; B1, B2, B3, and B4 = humid; r = small or no water deficiency; d = small or no water excess; s = moderate water excess in summer; = moderate water deficiency in winter; A′ = megathermal; B′2 = mesothermal). , where is the gap percentage, is the amount of missing data in the period, and is the amount of total data in the period. |
