WMO | Public Weather Services (PWS)
One of the principal roles of NMHSs if to provide to the general public and also to more specialized users, reliable and accurate weather products and services in support of safety and protection of people and goods at times of extreme weather phenomena as well as assisting in the efficient and economic pursuit of business and domestic activity of citizens.
These products and services are highly perishable goods and must be communicated and distributed in a timely manner to the users and to the public. To ensure that this information is received in the best possible manner, it is necessary that the public not only be able to take in and understand the message, but that they be attracted to the product and have sufficient interest and motivation to consult it, read it, listen to or look at it. Thus the manner of communication as well as the dissemination infrastructure both become equally important in order to achieve the optimum distribution of the information.
