Warm Fronts

If you know what a cold front is, understanding what a warm front is can be easier. If the circumstances are normal, the warm air can’t be displaced by cold air masses. Cold air masses are also named cold fronts and they can be denser than the warm air is.Sometimes, these cold fronts don’t bring weather changes with them. But, with enough moisture, the cold fronts can provoke thunderstorms and rain showers, which can last for many weeks.

Basically, a warm front is everything that a cold front isn’t. A warm front is the frontal area of a warm mass of air, which replaces the cool air. As one might expect, the air that exists in front of the mass of warm air is cool when compare with the air that exists behind them.

While cold fronts are known for their devastation effects, warm fronts are more docile. Here is one can expect when they see an approaching mass of warm air:

• Cold front temperature conditions are opposite to those from the warm fronts. When you’re expecting a warm front, you will notice the temperature being much cooler. When the mass of warm air passes, you will see that the temperature changes quickly and becomes warmer.
• You can expect stronger showers when there are cold fronts. With a warm front, you can expect drizzling and light showers. Still, the humidity is abundant, even though there is a drizzle.
• If you’re in the south hemisphere, the wind will blow from north to northeast. If you are in the northern hemisphere, you will notice the wind blowing from south to southeast. After the warm front has passed, the wind direction will shift.
• You will notice that the visibility drops during a warm front, making it hazier and poorer. There is also the chance of fog forming.
