Question 1

In forensic meteorology, when reconstructing past weather conditions for a slip-and-fall lawsuit, which data source is generally considered most legally defensible?

Accepted Answer

Archived ASOS/AWOS data from the nearest certified weather station

Answer

ASOS/AWOS data from FAA/NWS-certified automated surface observing stations provides calibrated, time-stamped records that meet legal standards for evidentiary reliability.

Question 2

A consulting meteorologist is hired to assess wind damage to a warehouse roof. The insured claims straight-line winds caused the damage, while the insurer suspects a tornado. Which observational signature would most strongly support the tornado hypothesis?

Accepted Answer

Convergent or rotational debris scatter pattern on the roof and surroundings

Answer

Tornadoes produce rotational or convergent debris patterns, while straight-line winds produce a more uniform, unidirectional debris scatter.

Question 3

When computing the probability that a historical weather event occurred at a specific location and time for litigation, what is the primary limitation of using gridded reanalysis data (e.g., NARR, ERA5)?

Accepted Answer

Spatial resolution may be too coarse to capture local microclimatic conditions

Answer

Reanalysis grids typically resolve at 12–32 km or coarser, which can miss local topographic or urban effects critical to site-specific forensic assessments.

Question 4

A CCM providing expert witness testimony about a hailstorm should most accurately describe hail size using which reference standard?

Accepted Answer

Comparison to common objects (pea, golf ball, grapefruit) per NWS standard sizes

Answer

The NWS uses standardized object comparisons (pea=0.25 in, quarter=1 in, golf ball=1.75 in, etc.) that are widely recognized and legally accepted for describing hail size.

Question 5

In an agricultural insurance dispute over crop freeze damage, which tool best determines whether a damaging temperature threshold was reached at canopy level rather than screen height?

Accepted Answer

Crop-level temperature sensors or agricultural weather station at plant height

Answer

Screen-height (2 m) temperatures can differ significantly from canopy temperatures due to radiative cooling at the surface, so crop-level sensors provide the most accurate freeze assessment.
