kausittaisten

Kausittaisten is Finnish for the genitive plural form of the adjective kausittainen, which means seasonal or periodic. The term is used to describe phenomena, events, or conditions that vary with seasons or other time periods. It appears in scientific and descriptive Finnish when discussing patterns that recur or depend on time, such as weather, disease incidence, markets, or ecological processes.

Etymology and grammar: The adjective kausittainen is formed from the noun kausi, meaning season or period, with the suffix -ttainen to indicate a characteristic or relation. In Finnish, adjectives agree with the noun they modify in number and case. Therefore, kausittainen becomes kausittaisten when used with a plural noun in the genitive case, for example kausittaisten ilmiöiden (of seasonal phenomena).

Usage: Kausittaisia phenomena are described as tied to particular seasons or time frames. The expression kausittaisten ilmiöiden avulla or kausittaisten ilmiöiden tutkimus refers to studying or addressing seasonal patterns. The term is common in disciplines such as meteorology, epidemiology, agriculture, energy planning, and economics, where understanding seasonal variation improves forecasting and decision-making.

Examples: Kausittaisten ilmiöiden esiintyvyys vaihtelee vuoden aika- ja sääolosuhteiden mukaan. Kausittaisten sairauksien, kuten influenssan, esiintyvyys on usein suurempi kylmillä kuukausilla. Tutkimuksessa tarkastellaan kausittaisten vaihtelujen vaikutusta energian kysyntään ja varastointiin.
