For each day, compute the average temperature (°C) using the recorded maximum and minimum temperatures.

Using the simplified heat‑index formula HI = T + 0.33 × RH – 0.70 × WS – 4.00 (where T is the average temperature in °C, RH is relative humidity in %, and WS is wind speed in km h⁻¹), calculate the heat index for each day. The wind speeds recorded were 12 km h⁻¹ (Day 1), 8 km h⁻¹ (Day 2) and 5 km h⁻¹ (Day 3). Identify the day with the highest heat index.

Based on the temperature trend and the change in wind direction (Day 1: from the southeast, Day 2: from the east, Day 3: from the north‑west), indicate which day most likely experienced the passage of a cold front and justify your answer.
( d )
Explain how high relative humidity influences the perceived temperature, referring to the heat‑index concept used above.
