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.
On a weather forecast map, a warm front is represented by a solid line with red semicircles pointing towards the colder air and in the direction of movement. Again, there is typically a noticeable temperature change from one side of the warm front to the other, much the same as a cold front. If colder air is replacing warmer air, it is a cold front, if warmer air is replacing cold air, then it is a warm front.
