2. Atmospheric Calculations Workflow

Calculate key atmospheric parameters for meteorology, climate science, and weather forecasting applications.

Workflow Steps:

1. Calculate Coriolis Parameter - Compute Earth's rotation effect
2. Calculate Geostrophic Wind - Determine wind from pressure gradients
3. Calculate Heat Index - Assess human heat stress
4. Calculate Potential Temperature - Standardize temperature measurements
5. Calculate Dewpoint - Determine moisture content

Implementation:

## Initialize client
client = AtmSciClient(
    "https://scp.intern-ai.org.cn/api/v1/mcp/35/AtmSci-Tool",
    "<your-api-key>"
)

if not await client.connect():
    print("connection failed")
    exit()

print("=== Atmospheric Science Calculations ===\n")

## Step 1: Calculate Coriolis parameter
print("Step 1: Coriolis Parameter")
latitude = 45.0  # degrees
result = await client.session.call_tool(
    "atm_calc_coriolis_parameter",
    arguments={"latitude": latitude}
)
result_data = client.parse_result(result)
print(f"Latitude: {latitude}°")
print(f"Coriolis parameter: {result_data} s⁻¹\n")

## Step 2: Calculate geostrophic wind
print("Step 2: Geostrophic Wind")
result = await client.session.call_tool(
    "atm_calc_geostrophic_wind",
    arguments={
        "pressure_gradient_x": 1.0,  # Pa/m
        "pressure_gradient_y": 0.5,  # Pa/m
        "latitude": latitude,
        "air_density": 1.225         # kg/m³
    }
)
result_data = client.parse_result(result)
print(f"Geostrophic wind (u, v): {result_data} m/s\n")

## Step 3: Calculate heat index

result =  client.session.call_tool(
    ,
    arguments={
        : ,

Physical Interpretations

Coriolis Parameter:

• Positive in Northern Hemisphere, negative in Southern
• Zero at equator, maximum at poles
• Critical for large-scale atmospheric circulation

Geostrophic Wind:

• Theoretical wind resulting from pressure gradient force and Coriolis effect
• Valid above atmospheric boundary layer
• Actual winds deviate due to friction and other forces

Heat Index:

• 80°F: Caution (fatigue possible)

• 90°F: Extreme caution (heat exhaustion possible)

• 103°F: Danger (heat stroke likely)

• 125°F: Extreme danger

Potential Temperature:

• Temperature air parcel would have if brought adiabatically to reference pressure (1000 hPa)
• Conserved for adiabatic processes
• Used to identify air masses and atmospheric stability

Dewpoint:

• Temperature at which air becomes saturated
• Higher dewpoint = more moisture
• Dewpoint > 65°F feels humid
• Dewpoint depression (T - Td) indicates saturation level
