The cold air has ice crystals. The warm air has water droplets. During the storm, the droplets and crystals bump together and move apart in the air. This rubbing makes static electrical charges in the clouds.

What causes electric charge in clouds?
Air molecules and suspended water droplets collide as they swirl around in the clouds. Warmer air and water droplets rise, carrying charges with them. The result is an excess of positive charge near the cloud tops, and an excess of negative charge in the bottom layers of the clouds.
What causes lightning to strike inside a cloud?
Lightning is an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves. Most lightning occurs within the clouds. ... This heat causes surrounding air to rapidly expand and vibrate, which creates the pealing thunder we hear a short time after seeing a lightning flash.
What causes lightning ions?
The strong electric field causes the air around the cloud to "break down," allowing current to flow in an attempt to neutralize the charge separation. ... The electric field causes the surrounding air to become separated into positive ions and electrons -- the air is ionized.
How do clouds create lightning?
This warm air rises. As the air rises, water vapour cools and forms a cloud. ... Heavier, negatively charged particles sink to the bottom of the cloud. When the positive and negative charges grow large enough, a giant spark - lightning - occurs between the two charges within the cloud.
Do lightning rods attract lightning?
Myth #9: Lightning rods attract lightning. Fact: Definitely not! A lightning protection system simply intercepts a lightning strike and provides a path to ground for discharging the dangerous electricity.
Why is there lightning but no thunder?
Thunder starts as a shockwave from the explosively expanding lightning channel when a large current causes rapid heating. However, it is possible that you might see lightning and not hear the thunder because it was too far away. Sometimes this is called “heat lightning” because it occurs most often in the summer.
Why is there lightning but no rain?
Dry thunderstorm refers to thunder and lightning that occur without bringing rain to the ground. In fact, the thunder-bearing clouds do produce rain but the rain droplets have evaporated in the air before reaching the ground. ... The anvil cloud is so high that rain coming from it evaporates before reaching the ground.
What determines where lightning strikes?
When a storm passes by and a bolt of lightning flashes, HAMMA can determine where the strike happened. It also measures the electric field produced by the strike. Its sensors can peer inside a cloud during that critical split-second before lightning develops.
What are lightning rods made of?
The main attribute common to all lightning rods is that they are all made of conductive materials, such as copper and aluminum. Copper and its alloys are the most common materials used in lightning protection.
What creates thunder and lightning?
Thunder is caused by the rapid expansion of the air surrounding the path of a lightning bolt. ... As lightning connects to the ground from the clouds, a second stroke of lightning will return from the ground to the clouds, following the same channel as the first strike.
How electric forces and electric fields interact in lightning?
As positive and negative charges begin to separate within the cloud, an electric field is generated between its top and base. ... When that charge threshold is reached, the strength of the electric field overpowers the atmosphere's insulating properties, and lightning results.
Does cloud to cloud lightning make thunder?
We also commonly see lightning strike from cloud to cloud, lightning flashes within the same cloud, and lightning that stretches from a cloud to the air around it. ... This answers our question: All lightning creates thunder because all lightning is hot enough to create that sonic boom.
Can lightning strike through a window?
Lightning can jump through windows, so keep your distance from them during storms! The second way lightning can enter a building is through pipes or wires. If the lightning strikes utility infrastructure, it can travel through those pipes or wires and enter your home that way.
Is it true that lightning can strike twice?
Myth: Lightning never strikes in one place twice. Fact: Actually, lightning can, and often does, strike the same place repeatedly — especially if it's a tall and isolated object. For example, the Empire State Building is hit about 25 times per year .
