Meteorologists want to design a system of instruments that will evaluate ocean air temperature and wind speed in order to predict catastrophic weather such as hurricane and cyclones what should they do before producing their first working system of instruments

Build a prototype

Explanation:

            A prototype may be defined as an early sample or a model or the release of the product that is built to test the concept or the process. It is generally made in use to evaluate some new design such as to enhance the precision by a system analysts and the users.

           Thus in the context, a Meteorologists who wishes to design an instrument to evaluate the air temperature of the ocean and the speed of the wind so as to predict hurricanes and cyclones should first built a prototype of his concept and test the process before the production of the first working system.

they absorb it i think

not sure
