Porterville Weather - Lapse Rate

        Insufficient Data to plot ELR1. Insufficient Data to plot ELR2.
      ELR = Environmental Lapse    Dew Temp       
      DALR = Dry Adiabatic              SALR = Saturated Adiabatic

1. Select ELR Station(s) and details:

      ELR 1:


      ELR 2:


2. Enter estimated maximum daytime Temperature in °C :
    (Maximum temperature yesterday = 36.6 °C)

3. Enter estimated Dewpoint Temperature in °C :             
    (Maximum Dewpoint yesterday = 13 °C)

4. Refresh.

5. Interpret.
    - Blue Day Ceiling: DALR crosses ELR.
    - Cu Day Base: SALR starts before DALR crosses ELR.
         Cloud Tops: SALR crosses ELR

Porterville Attractions - African Caper White Butterfly.

In South Africa the Pioneer Butterfly is also known as the African Caper White or Brown-Veined White.

It is well known during summer and autumn when large numbers migrate north-east over the interior. Such erratic migrations are probably more properly called ”eruptions”. When the population reaches a particularly high level and there's not enough food, the butterflies head off en masse to find new foraging grounds.

When they arrive in such large numbers the larvae remove all the leaves from thickets of Maerua and substantially change the vegetation dynamics of the areas they settle in.
