Biometeorological studies are not constrained by physical or temporal scales, nor by the strength of the atmospheric signal. These can range from minor random variability to extreme events, such as tropical cyclones, extreme ultraviolet radiation and thermal hazards. Clearly, within such broad boundaries biometeorology lends itself naturally to interdisciplinary research and collaboration.
Biometeorology is studied on an infinite number of geographical scales. An example of a large scale study would be the impact of climate change on human well-being. Biometeorology can also be studied on the micro scale: an investigation of the effects of temperature change on microorganisms living on the leaf of a plant is an example.
