 SINGAPORE - 5 FEB 2026: 7.21pm. The cumulonimbus clouds or thunderhead is often associated with severe weather like thunder, lightning and heavy rain. They appear as vertical growths extending from low altitudes to as high as 15 km. These clouds develop through convection, transporting heat and moisture high into the atmosphere. The orange and yellow colours are due to the sun setting, casting light through the clouds.

Cumulus clouds are puffy, cotton-like clouds with flat bases and rounded, cauliflower-like tops, often seen on sunny days, indicating fair weather, but can grow vertically into towering cumulus congestus and even cumulonimbus (thunderstorm) clouds with strong updrafts, signaling potential for rain or storms. Formed by rising warm air (uplift), their name comes from the Latin for "heap," and they range from small cumulus humilis (fair weather) to larger cumulus mediocris and towering congestus, showing vertical development.  

 

 

Characteristics

• Appearance: Brilliant white sunlit parts, flat dark bases, dense with sharp outlines, resembling cotton balls or cauliflower. 
• Formation: Result from warm, moist air rising and condensing at a uniform level, creating their flat base. 
• Altitude: Generally low-level, but congestus forms can rise to middle levels. 

Types & Weather Indicators

Cumulus humilis: Wider than tall, limited vertical growth, typically fair weather. 
Cumulus mediocris: Moderate vertical development, like a small heap. 
Cumulus congestus: Taller than wide, strong vertical growth, can produce showers and develop into cumulonimbus. 
Cumulonimbus: The mature thunderstorm cloud, formed from congestus, with dark bases and potential for lightning, hail, and tornadoes. 

Evolution

Small cumulus (humilis) indicate stable conditions.
Growing cumulus (mediocris, congestus) suggest increasing instability.
If updrafts are strong, they develop vertically into towering forms, potentially leading to thunderstorms.

4839. A 4-month-old red-eared slider is lethargic and has not been eating for 3 days

VET CASE  FEB 2026

Hello, I would like to check on terrapin treatments.

I have a 3–4 month old red-eared slider that has not been eating for around 3 days. It has been basking more than usual but it still goes into the water, just not moving around as much, seems lethargic, and I have noticed bubbles from its nose(a few times,not much)with heavier breathing at times. No visible eye swelling or mucus formed. I’m deciding to bring it to the vet if it still acts like this after a few more days, if it’s not too young to be treated.

May I check:
    1.    What is your consultation fee?
    2.    Roughly how much would diagnosis and treatment cost?

Please phone 6254-3326 for information.

Metabolic bone disease (MBD) is a common disease in pet red-eared sliders.
Other terms which may be used include fibrous osteodystrophy, osteomalacia, secondary nutritional hyperparathyroidism, osteoporosis, and rickets. There is no single cause of MBD and the disease is not as simple as calcium deficiency. The primary problem is a disruption of calcium metabolism which causes a host of related problems.

MBD is almost always a result of poor husbandry but it is also generally preventable by providing a proper environment and diet specifically for your type of reptile. 

Prevention of metabolic bone disease

Proper husbandry is more than just providing the right diet. The following are important in both the prevention and treatment of metabolic bone disease:

• A diet balanced in calcium and phosphorus, protein, energy and other nutrients. Buy a reputable brand with good supply of Calcium, Phosphorus and Vit D..
• Exposure to UVA/UVB invisible light rays
• Proper heat gradients - basking area heated at one end with heating lamp and UVA/UVB lights, the other end cooler temperature.
• Adequate enclosure and/or room to exercise

 TIPS:
I sat on the fitness corner exercise chair, rest my head on its top and point the camera at the moon, to stablilise my hands. If I hand hold the camera, it will be very difficult to get a sharp image. The settings from Brian Peck are important too: 

Basically, they are

Cumulus clouds are detached, white, fluffy clouds with cauliflower-like tops and flat bases, typically appearing in fair weather. Known as "heap" clouds, they form at low altitudes (below 2,000 m) due to convective, upward currents of warm air. They often appear in the morning, grow throughout the day, and evaporate by evening, though they can develop into tall cumulonimbus clouds. 

Key Characteristics and Types:

• Appearance: Distinct, sharp outlines with brilliant white, sunlit tops and darker bases.
• Formation: They are formed by thermal convection, where moist air rises and condenses, making them a sign of rising air currents.
• Species:
  • Cumulus humilis: Wide, flattened, and small, indicating fair weather.
  • Cumulus mediocris: Similar to humilis but with more vertical development.
  • Cumulus congestus (Towering Cumulus): Tall, cauliflower-shaped clouds that may produce rain and can develop into thunderstorms. 

Behavior and Weather Indicators:

• Fair Weather: Small, scattered cumulus clouds often signify pleasant conditions.
• Vertical Growth: If they grow vertically, they can indicate instability and develop into cumulonimbus clouds, producing showers.
• Diurnal Cycle: Over land, they form during the day due to solar heating and dissipate in the evening.
• Turbulence: They are often associated with turbulent air, which can cause bumpy flights for small aircraft.
