This paper describes conceptual dynamicity as reflected in the verbs in specialized texts. All the examples used to illustrate this phenomenon are taken from a corpus of meteorological texts, and are typical of processes and actions within the TROPICAL CYCLONE frame. In this study, we analyze verb meaning as well as argument structure. Our results show that the basic meaning of each verb profiles the meaning of the term tropical cyclone in different ways, and provides a way to access the multidimensionality of terms and the concepts they designate. We also classify the verbs most frequently activated by TROPICAL CYCLONE in lexical domains since verbs with similar meaning also have similar argument structure. This method of studying terms in conjunction with the verbs that most frequently activate them is crucial for the representation of conceptual information, and is connected with the network of semantic relations that is activated by a specialized concept.
