Differences in air pressure are generally what has the greatest influence on wind speed, so your answer would be air mass.

Which has the greatest effect on wind speed Quizizz?
Rainy weather causes greater wind speeds. Warmer weather causes greater wind speeds. Differences in air pressure cause greater wind speeds.
What is an influence on wind speed?
The speed and direction of the wind is governed by three forces; the pressure gradient force (PGF), the Coriolis Force and friction. PGF is the force produced by differences in barometric pressure between two locations and is responsible for the flow of air from an area of high pressure to an area of low pressure.
What affects the wind?
Explain how the Coriolis effect, friction, and pressure gradients affect wind direction. Wind is the product of pressure gradients established between high and low pressure systems. These systems are constantly moving and changing. This constant movement of the pressure systems is due to the Coriolis effect.
Why is there so much wind lately?
We have high pressure (usually meaning sunny/clear skies) and we have low pressure (which brings clouds, rain and storms). Weather is nature’s attempt to balance. So high pressure, where we have an excess of pressure, always flows toward lower pressure. More storm systems, the more frequent windy days.
What is the primary cause of winds?
The wind is caused by differences in atmospheric pressure which is mainly caused by temperature difference. When a difference in atmospheric pressure exists, air moves from the higher to the lower pressure area, resulting in winds of various speeds.
What are the 4 types of winds?
The four major wind systems are the Polar and Tropical Easterlies, the Prevailing Westerlies and the Intertropical Convergence Zone. These are also wind belts. There are three other types of wind belts, also. They are called Trade Winds, Doldrums, and Horse Latitudes.
What are the three main causes of wind?
Wind is the movement of air, caused by the uneven heating of the Earth by the sun and the Earth’s own rotation. Winds range from light breezes to natural hazards such as hurricanes and tornadoes.
What makes wind stronger or weaker?
Strong winds are due to a strong pressure gradient force. A pressure gradient is how fast pressure changes over distance. So, when pressure changes rapidly over a small distance, the pressure gradient force is large. Strong winds almost always result from large pressure gradients.
What is the root cause of wind?
The Short Answer: Gases move from high-pressure areas to low-pressure areas. And the bigger the difference between the pressures, the faster the air will move from the high to the low pressure. That rush of air is the wind we experience.
What is strong wind called?
A very strong wind is called storm.
Does wind ever stop?
The wind speed tends to decrease after sunset because at night the surface of the Earth cools much more rapidly than does the air above the surface. As a result of this difference in cooling ability, it doesn’t take long for the ground to become colder than the air above it.
Why does the wind never stop blowing?
Wind is simply high pressure moving towards low pressure. Wind is the atmosphere trying to reach a pressure equilibrium. If the pressure is equalized, there will be no more wind. Which is rare on our planet as different areas are always heating and cooling.
Why is the wind stronger at night?
In the morning, when sunlight returns and begins to warm the surface layer, the wind from above gradually builds downward and returns to the surface. At night, winds above the surface layer often increase in strength because its energy is not dissipated by contact with the ground.
What can the wind not do?
The winds do not harm us. We bow before them and so we do not break. You, in all your pride and strength, have so far resisted their blows. When there is a strong wind, all the things that are weak fall and get crushed.
Does Earth rotation cause wind?
Our planet’s rotation produces a force on all bodies moving relative to theEarth. The force, called the “Coriolis effect,” causes the direction of winds and ocean currents to be deflected.
Where is there no wind?
Astronomers Find the Calmest Place On Earth 231 They have pinpointed the coldest, driest, calmest place on earth, known simply as Ridge A, 13,297 feet high on the Antarctic Plateau. ‘It’s so calm that there’s almost no wind or weather there at all,’ says study leader Will Saunders, of the Anglo-Australian Observatory.
What is the calmest place on Earth?
Scientists have discovered that the calmest place on Earth is on top of a vast icy plateau in Antarctica. According to a report in the Times, scientists pinpointed a site, known simply as Ridge A, high up on the Antarctic Plateau, several hundred miles from the South Pole.
