What are the conditions needed for a blizzard?

Three things are needed for a blizzard to occur, cold air at the surface, lots of moisture, and lift:
  • Cold air (below freezing) – In order for there to be snowfall, the air temperature both up in the clouds and down at ground level must be cold.
  • Moisture – This is known as water vapor.

Furthermore, what constitutes a blizzard warning?

A Blizzard Warning (SAME code: BZW) is an advisory issued by the National Weather Service of the United States which means sustained winds or frequent gusts of 35 mph / 15 m/s or greater with heavy snow is forecast for a period of 3 hours or more.

Secondly, what makes a blizzard dangerous? A blizzard forms when heavy snow falls and strong winds blow the snow around, making it hard to see. Blizzards are extremely dangerous because people can lose their way in the blinding snow. The strong winds in a blizzard can also cause power outages, and cold temperatures can freeze water pipes.

Beside this, what are the right conditions for snow?

Snow forms when the atmospheric temperature is at or below freezing (0 degrees Celsius or 32 degrees Fahrenheit) and there is a minimum amount of moisture in the air. If the ground temperature is at or below freezing, the snow will reach the ground.

What causes a hurricane to die?

One of the driving forces of a hurricane is heat energy in oceanic surface waters. Warm water evaporates more quickly, and warm air rises. If it moves onto land it loses that warm water source, and so dies down. The single most important factor in a hurricane losing energy is friction.
