These questions all relate to the long-term goal of your research, which should be an important undercurrent of the proposal. Again, they should be a logical extension of the research question, hypotheses, and specific aims. It is also helpful to have a long-term plan for your own career development.
The effects from a cold front can last from hours to days. The air behind the front is cooler than the air it is replacing and the warm air is forced to rise, so it cools. As the cooler air canâ²t hold as much moisture as warm air, clouds form and rain occurs.
The sloping of warm air over the cold air leads to a forced uplifting (frontal lifting) of the warm air if one air mass is moving toward the other. In turn, this uplifting causes condensation to occur and the possibility of precipitation along the frontal boundary. Frontal zones where the air masses are not moving against each other are called stationary fronts. In transitional areas where there is some air mass movement, cold or warm fronts can develop. Figure 7r-2 illustrates a vertical cross-section of a cold front.
