Climate & Weather

Understanding our variable and changing climate is critical for managing resources and reducing risks.

Drought forecasting dashboard

NIWA and MPI are working together to develop a new drought forecasting tool. It uses innovative climate modelling, the latest in machine learning and other data-driven techniques to predict rainfall 35 days ahead. It will help farmers and growers better prepare for periods of dryness and drought.

    PICT (Past Interpretation of Climate) tool

    The Past Interpretation of Climate Tool (PICT) is an interactive platform that "allows palaeoclimate researchers to interpret data in terms of atmospheric circulation (AC) patterns and how those patterns relate to synoptic weather types".
