Which process describes air rising over mountains causing precipitation on the windward side?
Advection
Orographic lift
Convection
Frontal uplift
Orographic lift occurs when air is forced upward by terrain such as mountain ranges. As it rises, it cools and moisture condenses, leading to precipitation on the windward slope. The leeward side often experiences a rain shadow. More details at .
What is the main driver of global wind patterns?
Lunar gravity
Earth's magnetic field
Ocean currents
Solar heating causing pressure differences
Solar heating warms the equator more than the poles, creating pressure gradients that drive global wind circulation. Air rises at the equator and moves poleward aloft, then sinks in subtropical regions. Coriolis effect and Earth's rotation modify the flow into prevailing wind belts. See .
What atmospheric layer is temperature inversion most commonly found near the Earth's surface?
Troposphere
Stratosphere
Thermosphere
Mesosphere
Surface-based temperature inversions occur in the lowest atmospheric layer - the troposphere - when ground cooling at night chills air near the surface.

Convective Available Potential Energy; it measures the buoyant energy available for convection
Cloud Accumulation Precipitation Estimate; it measures precipitation potential
Cumulus Activation Potential Estimate; it measures cloud formation likelihood
Cyclonic Angular Potential Energy; it measures rotational wind energy
CAPE quantifies the buoyant energy an air parcel has if lifted vertically, indicating thunderstorm potential. Higher CAPE values correlate with stronger updrafts and severe weather risk. Meteorologists use it to assess convective storm development. See .
In a skew-T log-P diagram, what does the dry adiabatic lapse rate line represent?
The line of constant dew point
The line of constant pressure
The environmental lapse rate
The rate at which a rising unsaturated air parcel cools
The dry adiabatic lapse rate is the rate at which unsaturated air cools at about 9.8 °C per kilometer when lifted. It is plotted as straight lines on a skew-T log-P diagram and used to assess parcel stability. If the environmental lapse rate is steeper, the atmosphere is unstable. For more, see .
What is baroclinic instability and why is it important in mid-latitude weather systems?
The process of radiative cooling at night, forming inversions
The advection of dry air aloft, producing clear skies
The growth of atmospheric waves due to horizontal temperature gradients, leading to cyclones
The vertical mixing of air in the tropics, causing thunderstorms
Baroclinic instability arises where temperature gradients exist, such as between warm and cold air masses, leading to the growth of mid-latitude cyclones. It drives the wave patterns seen in jet streams and frontal systems. Without it, major storm systems would not develop. Read more at .
Which radar product is most useful for identifying rotation within a thunderstorm?
Dual-polarization ratio
Echo tops
Reflectivity
Velocity
Doppler radar velocity products display radial velocities of precipitation targets, indicating inbound and outbound motion. Rotational signatures appear as adjacent areas of red and green velocities. Reflectivity shows precipitation intensity but not motion. Learn more at .
What causes a temperature inversion in the stratosphere?
Radiative cooling of the surface at night
Absorption of ultraviolet radiation by ozone
Strong convective mixing
Latent heat release from condensation
Ozone in the stratosphere absorbs UV radiation, warming this layer and creating a temperature inversion above the cooler tropopause. This inversion inhibits vertical mixing and defines the boundary between the troposphere and stratosphere. Surface inversions have different causes. More at .
Which jet stream is situated closest to the equator?
Polar jet stream
Subtropical jet stream
Ferrel jet stream
Tropical easterly jet
The subtropical jet stream forms near the tropopause around 30° latitude in both hemispheres and is closest to the equator. The polar jet stream sits poleward of it, near 60° latitude. These fast air currents influence weather patterns and storm tracks. See .
What is the significance of potential vorticity conservation in atmospheric dynamics?
It determines the onset of convection and thunderstorm initiation
It calibrates satellite-derived temperature profiles
It constrains the evolution of large-scale atmospheric flow and links rotation with stratification
It measures the humidity profile of the atmosphere
Potential vorticity combines fluid rotation and stratification into a single conserved quantity in the absence of friction and diabatic processes. Its conservation explains why cyclones and anticyclones evolve along certain paths and how air columns stretch or compress. It is fundamental to balanced atmospheric models. For details, see .
Which type of atmospheric wave is most directly associated with the Madden - Julian Oscillation?
Gravity wave
Mixed Rossby - gravity wave
Rossby wave
Kelvin wave
The MJO is characterized by an eastward-propagating envelope of enhanced and suppressed tropical rainfall linked to equatorial Kelvin waves. These waves help modulate convection on timescales of 30 - 60 days. Rossby and gravity waves also play roles, but Kelvin waves dominate the oscillation's propagation. Learn more at .

Cheat Sheet

  1. Water Cycle and Latent Heat -

    Mastering the stages of the water cycle (evaporation, condensation, precipitation, collection) is essential for the meteorology science olympiad; latent heat released during condensation powers thunderstorms and convection. Mnemonic "Every Cloud Brings Precious Rain" helps recall the sequence. Understanding these energy exchanges informs weather pattern analysis (source: NOAA).

  2. Atmospheric Pressure and the Ideal Gas Law -

    The Ideal Gas Law (PV = nRT) describes how pressure, volume, and temperature interact in the atmosphere, with direct application to barometric readings and altitude adjustments. For example, a rising parcel will cool at the dry adiabatic lapse rate (~9.8 °C/km) when pressure drops. Mastering this formula boosts accuracy in pressure-based meteorology quiz questions (source: American Meteorological Society).

  3. Coriolis Effect and Geostrophic Wind -

    The Coriolis parameter f = 2Ω sinφ explains why winds deflect right in the Northern Hemisphere and left in the Southern Hemisphere, balancing pressure-gradient forces to create geostrophic wind. Remember the phrase "Right in North" to lock in hemisphere deflection. This principle underlies large-scale wind patterns tested in the free meteorology quiz (source: University of Wisconsin - Madison).

  4. Frontal Boundaries and Station Models -

    Identifying cold, warm, occluded, and stationary fronts on a synoptic chart is key: cold fronts have blue triangles, warm fronts red semicircles. Practice reading station models - plot temperature, dew point, wind barbs, and pressure trend symbols - to interpret real-time data. Effective use of these skills earns top marks in your science olympiad meteorology quiz (source: National Weather Service).

  5. Satellite Imagery and Forecasting Tools -

    Visible, infrared, and water-vapor satellite imagery provide cloud cover, surface temperature, and moisture profiles critical for short-term forecasting. Tools like the Rossby Wave pattern help predict jet-stream shifts, while GOES satellites deliver live updates. Familiarity with these resources elevates your forecasting accuracy and confidence (source: NASA).
