How thunderstorms can REDUCE heat damage to your garden

After a week of record-breaking heat in the UK, many Britons’ gardens will look a bit run down.

But if your grass looks more brown than green, there’s good news: Thunderstorms are expected in parts of the UK tomorrow.

Thunderstorms can help plants grow not only because of the rain they bring, but also because of the associated lightning strikes.

Lightning strikes cause nitrogen in the air to bond with oxygen, creating nitrogen oxides.

They combine with moisture in the air and fall as rain, providing plants with the nitrate-rich water they need to grow.

People living in Wales, South West England and Central South England will benefit as the Met Office forecasts thunderstorms for tomorrow.

Slow torrential rains and thunderstorms are possible in some places on Friday.

Thunderstorms can help plants grow not only because of the rain they bring, but also because of the associated lightning strikes.

How does lightning help plants grow?

Plants require nitrogen for a number of important processes, including photosynthesis, tissue and cell growth, and protein formation.

Although the air in Earth’s atmosphere is about 78% nitrogen, a process called nitrogen fixation is necessary for plants to take it up.

Much of this process can be done by bacteria and algae. However, lightning can also fix nitrogen.

“Extreme heat from a lightning strike causes nitrogen to bond with oxygen to form nitrogen oxides,” the Met Office explains.

‘[This] combines with air moisture, falls in the form of rain and watering plants with water rich in nitrates.

Thunderstorms usually happen after hot weather because the atmosphere is “unstable”, according to the Met Office.

At this time, the ground is very warm, and colder air moves over it.

Speaking to MailOnline, a Met Office spokesman explained: “This colder air on top of warmer air near the surface creates an unstable atmosphere.

“In this situation, the air rises rapidly, cools, and large, towering thunderclouds called cumulonimbus clouds can form.”

As the warm air continues to rise, the water droplets combine to form larger droplets that freeze to form ice crystals.

Eventually, the droplets become too heavy to be supported by the upward movement of air, and they fall in the form of hail.

The Met Office explains that as hail travels within a cloud, it acquires a negative charge by rubbing against smaller, positively charged ice crystals.

“A negative charge forms at the base of the cloud where hail collects, while lighter ice crystals remain at the top of the cloud and create a positive charge,” the report said.

“Negative charge is attracted to the surface of the Earth, other clouds and objects.

“When the attraction gets too strong, the positive and negative charges combine or discharge to balance the difference in a lightning flash, sometimes called a lightning strike or thunderbolt.”

The Met Office has issued a yellow thunderstorm warning for parts of Wales, South West England and Central South England for tomorrow.

In news that will be welcomed by Brits whose gardens have been decimated by the heatwave, lightning could help other plants grow.

What is a yellow alert?

The Met Office issues color-coded weather warnings when severe weather could affect people in the UK.

A yellow storm warning means the weather will cause some low level impacts, including some traffic obstruction in several locations.

What to expect:

– Splashes and flash floods can lead to difficult driving conditions and road closures.

– In the event of flooding or lightning strikes, there may be delays and some cancellations of trains and buses.

– There is a small possibility that power outages may occur and other services for some homes and businesses may be lost.

The rapid expansion and heating of the air caused by lightning causes loud peals of thunder.

Unfortunately, trees can often be destroyed by lightning strikes.

“When lightning strikes a tree, it usually travels just below the bark of the tree, where there is a layer of sap and water,” the Met Office explains on its website.

“This layer instantly heats up and expands, causing the bark to come off the tree and sometimes split the wood.”

However, lightning can also help other plants grow.

Plants require nitrogen for a number of important processes, including photosynthesis, tissue and cell growth, and protein formation.

While the air in Earth’s atmosphere is about 78 percent nitrogen, its uptake by plants requires a process called nitrogen fixation, a process by which nitrogen is removed from its molecular form in the atmosphere and converted into nitrogen compounds. useful for other biochemical processes.

Much of this process can be done by bacteria and algae.

However, lightning can also fix nitrogen.

“Extreme heat from a lightning strike causes nitrogen to bond with oxygen to form nitrogen oxides,” the Met Office explains.

As record temperatures of up to 40.3C (104.5F) sweep the UK this week, many Britons will see their gardens wither.

Sadly, the Royal Horticultural Society has said these extreme temperatures could mean the end of the traditional British garden.

“Extreme weather could be a catalyst for change in what we consider the traditional British garden,” said Leigh Hunt, RHS chief adviser, in an interview. The keeper.

“For years, gardeners have been growing more light-loving and drought-tolerant plants in their gardens, but summer 2022, and the expected damage this will do to some favorites, could lead to a more permanent shift to plants that can handle both extremes. wet and dry.’

Mr. Hunt advises gardeners to choose plants that are better suited to hotter conditions.

“For those experiencing plant losses this year, we would not recommend swapping like for like, but instead choosing plants that can handle hotter conditions, don’t need to be watered this summer, and can withstand prolonged wet conditions in winter,” said he.

“Examples include Burning Daylight daylily, Kleine Fontäne eulalia, and geranium.”

WHAT IS THE NITROGEN CYCLE?

Nitrogen (N) makes up almost 80 percent of our atmosphere and is essential for plants and animals.

The carbon-nitrogen bond is one of the most common in organic chemistry.

Animals need it to make proteins, which make up everything we need to live.

In plants, it forms the basis of enzymes, proteins and chlorophyll.

Ecosystems need nitrogen and other nutrients to absorb atmospheric carbon dioxide pollutants, and these are limited in plants and soil.

However, it is inert and most beneficial to life when converted to nitrates or nitrogen compounds.

The nitrogen cycle is a process in which an element is used and then returned to the system.

Nitrogen-fixing organisms convert nitrogen from the air into the soil.

Clarification is another way of getting nitrogen into the soil from the air.

Nitrification is the process by which ammonia (a compound of nitrogen and hydrogen) found in the soil is converted to nitrate by bacteria.

Plants then absorb these nitrates through their roots.

When the plant dies, this nitrogen returns to the soil.

Alternatively, if the plant is eaten by animals, the nitrogen is returned to the soil with their waste products.
