Effect of instabilities of flow on mesoscale predictability of weather systems

摘要: The numerical solution of Boussinesq equations is worked out as an initial-value problem to study the effect instabilities flow on initial error growth and mesoscale predictability. development weather systems depends different dynamic instability mechanisms according spatial scales system determined by symmetric instability. Since dominates among three types instability, it makes prediction associated more sensitive uncertainties. This indicates that stronger leads faster thus limits Besides impact thermodynamic also explored. evolvement convective manifests dramatic variation in small scale short temporal scale, furthermore, exhibits upscale growth. these features determine growth, arising from are less predictable predictability larger scales. latent heating responsible for changing stability subsequently influencing
