What GCSEs do you need to become a meteorologist

I'm taking triple science but I was wondering if you have to take computer science face to become a meteorologist

How does Doppler radar work?

Sorry if this is a stupid question but I don't understand it. How can we see the weather like that? Google's explanation is:

"The radar's computers measure the phase change of the reflected pulse of energy which then convert that change to a velocity of the object."

That sounds like it's from science fiction lol can someone ELI5?

Leisure book recommendation for a beginner

Hey. Im new to meteorology. Ive always been interested in the weather, and even more so during my ongoing physics degree. Unfortunately, I currently dont have the time/capacity to read through a thorough textbook on the subject, so my question is:

Are there any "leisure" books on the subject that delve into various aspects of meteorology, interesting phenomena and natural hazards to keep up my interest (my local weather has been stale for months on end), and introduce me to this subject in a less rigorous way than a textbook would? Something along the lines of "For the Love of Physics" by Walter Lewin, but for meteorology. Or maybe a even a hobbyist book that fulfills my criteria?

Why is the marine layer so random in Uk cold spells?

Living within the coast I have noticed that our probability of snow (whilst not actually uncommon in a typical winter) is completely random and not based on the parameters that would be usually used elsewhere to determine precipitation type.

For example, right now, we have the following:

  • -7c 850hPa at roughly 1360 metres or 4,500 feet.

  • 516 decametre

  • -40c at 500hpa (as low as -42c in some places)

But what do we have? A marine layer or very saturated layer of air about 2,000 feet in the air.

Anywhere else in the world this airmass would be subzero temps and a lot of snow but here we have heavy rain and 3c.

This is so inconsistent though. Sometimes this airmass does bring that snow/ice.

Look at the beautiful extratropical cyclone!

It’s even developing an eye wall.

Depending on the models you look at I have seen central pressures of 938 to 941 hPa! That’s category 4 hurricane territory. Thank goodness it’s not coming ashore. It’s going to be exerting a still not inconsequential amount of influence even from way out at sea.

All about mountain waves

Is there a classification system based on the severity of downslope wind events? Has anyone ever looked into what the theoretical maximum would be for a downslope wind event in the US?

Does anyone know where I can find weather themed phone cases? All I can ever find is "weather resistsent" phone cases and a limited selection of hyper realistic image ones. I'm speficially looking for a s24+ case right now incase anyone is wondering

How many bomb cyclones in North Pacific over time?

How common are bomb cyclones in the north pacific and how has their frequency changed over time?

Anyone have a source or record on how many have occurred in the past (example) 1, 5, 10, 30, 70 years?

Mi hanno regalato un corso per "diventare" tecnico meteorologo AMPRO, ma vorrei sapere se effettivamente vale i soldi che han speso.

Regalo di compleanno apprezzato, solo che cercando online non ho trovato nessun tipo di recensione o informazione aggiuntiva, se non la pagina introduttiva del corso.

Volevo solo sapere se è effettivamente un corso utile anche per poi cercare lavoro in futuro.

Why do coastal polar areas have so little cloud cover?

(I realise this query sits more within climatology than meteorology, but r/climate seems understandably concerned with bigger questions.)

The Wikipedia article on cloud cover provides a map of global average cloud cover at the top of the article. A lot of it is fairly unsurprising - the Sahara is sunny, temperate and tropical climates are pretty cloudy, oceans are a bit cloudier than adjacent continents. However, what strikes me is that coastal areas in the polar regions (Ellesmere Island, Greenland, and coastal Antarctica) have cloud cover levels apparently closer to those of the Mediterranean or Southern US than to those of nearby inland or ocean regions. Does this mean these areas have naturally much clearer skies, and if so how come?

Wanting to move from weather underground, any forecast apps you’d recommend?

I've got a PWS so I've got great real time/past data, RadarScope, GOES etc but, while weather underground forecast has been sufficient for me for a long time (before and after IBM) I can't help but wonder if there is something better.

Why do cold frontal systems often result in virga?

Today, we had a depression overhead. There is a lot of precipitation on the radar but all that is falling is sprinkles.

Looking on the traffic cams there is heavy snow above about 300 metres of elevation but little falling at sea level. Obviously this points to an area of dry air at the surface.

Why does this form in these kinds of synoptic situations?

Would any/all of you please respond to this weather product review survey?

I am a student currently working on a capstone engineering product. For this I am working to design an Adaptive Forecasting weather station, i.e. a weather station that can make predictions about the weather as the parameters change. This survey will help me and my team review market viability for this product. Thank you to all who respond!

Calculating surface turbulent latent heat flux using ERA5 data?

The surface latent heat variables present in the ERA5 dataset don't really match the I'm looking for since surface turbulent latent heat (from what I know) is just over the oceans.

I've found certain formulas for surface turbulent latent heat like this one (https://www.frontiersin.org/journals/marine-science/articles/10.3389/fmars.2024.1431718/full) but I can't seem to find the perfect ERA5 variables for it.

Any help? Maybe a different dataset which directly gives surface turbulent latent heat? Or maybe I just have to modify ERA5's surface latent heat a bit to get what I'm looking for?

Looking to change major from Mech. Eng. to Atmos. Sci need some advice

I am currently a sophomore in college going down the BSME (Bachelors of Mechanical engineering) path and I have thought this was what I had been wanting to do my whole life. However, once I got here I realized it's not all that I thought it was. It is extremely difficult math and sciences while I am not good at math at all. So I did some research and I noticed my university has a "Atmospheric and Earth Science" degree. I did some searching into the classes required and they all seem really interesting. I was curious if anyone had a similar experience and if you have if you could give me some advice. I haven't changed majors yet but I am seriously considering it because I have always found weather and what happens in the atmosphere to be super interesting. Thanks all :)

General rule for cigar shaped cloud structures?

I get stumped identifying the phenomenon behind clouds that generally resemble a collection of cigars.

There are two candidate mechanisms, rolling convection (like cloud streets) on the long axis and wave phenomena on the short axis. Is there a general rule to differentiate, or do I just need to memorize each on a case by case?

Problems with ERA5 data

I using OpenGrADS-2.2 to plot a map about a geopotential anomaly at 700hpa but I can't reaply open file to do it.

I downloaded de Data from ERA 5 wich I hard some people are having problems with.

I would appreciate some advice.

Can you study meteorology if you had a C average in math?

Freshman in college here looking to get a degree related to meteorology. wasn't really sure where else to ask this since i've never posted on Reddit before.

I want to try to get a job or study weather but I never excelled in math and have always maintained a low "c" average. the only topic I was relatively good at was anything algebra related. with trig being the worst when it came to me understanding it. I know there's A LOT of math required for this so I'm not sure how much I'm going to struggle or if I should consider another career path.

The only reason I might try anyway is because I have always been obsessed with weather and loved talking about it ever since I was a kid. I have been considering this for years now. is it possible to still get a job in this area while being ok at best with math? or what could I expect to be studying if I were to go through with this?

Courses on Numerical Methods

Hello, I have a Bc's degree in Hydrometeorology (with a major in Meteorology & Climatology). So, I know the basics, but I have never been deeply interested in these subjects.

However, recently I’ve become curious about models, and I feel that I lack knowledge in this area.

Do you have any recommendations for courses on mathematical models / numerical methods for meteorologists / climatologists?
