The parameters in the following list are divided into parameters which are absolutely necessary for the diagnosis of a Cold Front (Key Parameters), parameters which give more information about the Cold Front (Supporting Parameters) and parameters which are not essential.
Choose the parameters you regard as Key Parameters for a Cold Front from the list below and submit your choice by clicking on the button at the bottom!
