Worldclim19个生物气候变量

生物气候变量源自每月的温度和降雨量值,以生成更具生物学意义的变量。这些通常用于物种分布建模和相关的生态建模技术。生物气候变量代表年趋势(例如,年平均温度、年降水量)季节性(例如,温度和降水的年变化范围)和极端或限制性环境因素(例如,最冷和最热月份的温度,以及潮湿和降水的降水)。干区)。一个季度是三个月(一年的 1/4)。 

BIO1 = Annual Mean Temperature

BIO2 = Mean Diurnal Range (Mean of monthly (max temp - min temp))

BIO3 = Isothermality (BIO2/BIO7) (×100)

BIO4 = Temperature Seasonality (standard deviation ×100)

BIO5 = Max Temperature of Warmest Month

BIO6 = Min Temperature of Coldest Month

BIO7 = Temperature Annual Range (BIO5-BIO6)

BIO8 = Mean Temperature of Wettest Quarter

BIO9 = Mean Temperature of Driest Quarter

BIO10 = Mean Temperature of Warmest Quarter

BIO11 = Mean Temperature of Coldest Quarter

BIO12 = Annual Precipitation

BIO13 = Precipitation of Wettest Month

BIO14 = Precipitation of Driest Month
