What is Bioclimatic variables?
Bioclimatic variables (Environmental variables) Bioclimatic variables are derived from the monthly temperature and rainfall values in order to generate more biologically meaningful variables. These are often used in species distribution modeling and related ecological modeling techniques.
How do you calculate seasonality temperature?
Bio 4a—Temperature Seasonality (CV) CV is calculated by first averaging the minimum temperature and maximum temperature val- ues for each month. Then the standard deviation of the 12 mean monthly temperature values is calculated.
What is seasonal temperature range?
Annual temperature range The annual range is defined as the difference between the hottest and coldest months, taking monthly mean temperatures in each case. It is given approximately by the difference between the average of the January maximum and minimum temperatures, and the corresponding average for July (6).
What is seasonality in climate?
For the purpose of relating climate to fire, seasonality has been defined variously as the number of months with rainfall under a variable threshold (such as 100 mm, as in Van de Werf et al., 2008), the number of months accounting for less than some percentage of mean annual precipitation (MAP; Archibald et al., 2009).
How did Koppen classify climates?
The Köppen climate classification scheme divides climates into five main climate groups: A (tropical), B (dry), C (temperate), D (continental), and E (polar). The second letter indicates the seasonal precipitation type, while the third letter indicates the level of heat.
How do I cite WorldClim data?

How do you explain seasonality?
Seasonality is a characteristic of a time series in which the data experiences regular and predictable changes that recur every calendar year. Any predictable fluctuation or pattern that recurs or repeats over a one-year period is said to be seasonal.
