Document Summary
Synoptic meteorology: study of large-scale systems and their driving mechanisms, given in real time. Large scale= 1000-6000 km, lasting a day to a week and moving at about 10 ms^-1. Wind is a combination of here components: n/s, e/w, and vertical. Pressure decreases with height, meaning that and w have an inverse relationship. Draw isobars along evenly spaced pressure gradients, and isotherms along evenly spaced temperature gradients, making the lines flow smoothly. Fronts can be determined by changes in wind direction, cloud cover, temperature and, in some cases, pressure. Model initialization is the process by which the system determines the necessary model parameters for the chosen forecast model. Sample factors are previous models and current observations. Objective analysis is the gridded representation of irregularly spaced observations, which is needed to transform observations to a regular format which the models can then use to run predictions.
