Gce Model Questions Vol1 2024 Geography Question 22

A city records the following daily maximum and minimum temperatures (°C) over a week: Day 1 30/20, Day 2 32/21, Day 3 31/19, Day 4 33/22, Day 5 34/23, Day 6 35/22, Day 7 33/21. The relative humidity at the maximum temperature is 60 % each day and at the minimum temperature is 80 % each day. Approximate the daily mean temperature as the average of the max and min, and the daily mean relative humidity as the average of the two humidity values. Using the heat‑index formula (HI = T + 0.33e - 0.70v - 4.00), where (e = \frac{RH}{100}\times6.105\times\exp\!\left(\frac{17.27T}{237.7+T}\right)\) (hPa) and wind speed (v) is a constant 2 m s⁻¹, identify the day with the highest heat index and give the heat‑index value (rounded to the nearest °C).
