I need a little help with scientific weather words. It's hard to describe what i mean but things like a fire front and so on to describe a bushfire and the weather around it.

Here are some common terms used in the business of wild fire and fire weather
"wildland fires" is the common term used for these types of fire.
The weather around or associated is known as "fire weather"
When condition becomes supportive for fires to grow rapidly in size and overage (usually a combination of strong gusty winds, low humidity, and dry fuels like vegetation, the conditions are said to be "critical".
Here are are some important terms that are commonly used in fire weather and wild fire protection and prevention program.
The boundary of where a control fire is allow to burn until it burns itself out or until it is put out by the fire crew is called a "fire line"
Te movement of the air around a fire will usually be air that flows up a hill or a mountain is known as "upslope winds" or "up canyon winds " and the winds coming down the side of of a hill or mountain is known as down slope winds" or "drainage winds" Other conditions associated movement of air includes these terms:
- Ridge top winds - the winds found at the top of a mountain or mountain range is of concern because strong winds above would produce conditions that can help spread a fire by lowering the pressure near the ridge resulting in stronger upslope winds. Also, strong winds aloft can mixed down during the day when heating of the surface will produce convective currents. It is the sinking of a column of air that will bring down this stronger winds can result in strong gusty afternoon winds. Strong gusty winds can whip a fire and run through a control fire line.
When fire conditions is expected to becomes within 24 to 36 hours. a "Fire Weather Watch" is issued. When these conditions are expected within 24 hours or if weather condition and fuels suddenly become critical for wildland fire, a "Red Flag Warning" is issued.

Hot and dry with no rain in sight. Localized smoke causing hazy air conditions.
