Climate

Climate affects sectors in society in a number of ways. These effects may be direct, as with heat stress, or indirect, as with infectious diseases such as malaria and meningitis.

This facility aims to explore and inform users about the climate-society relationship with an emphasis on the seasonal nature of that relationship, where appropriate.

Climate Analysis
Rainfall (1981-2019) and temperature (1961-2019) time series reconstructed from station observations and remote sensing proxies. This interface allows users to view rainfall, maximum and minimum temperature climatologies and anomalies.
This interface allows users to view rainfall, maximum and minimum temperature climatologies (1981-2019) and anomalies (1961-2019).
The Maproom explores historical daily precipitation by calculating simple seasonal statistics.
The Maproom explores historical daily temperature by calculating simple seasonal statistics.
This interface allows users to view rainfall, maximum, minimum and mean temperature seasonal climatologies, anomalies and probability of exceedance.
This interface allows users to view rainfall, maximum, minimum and mean temperature seasonal trends expressed per year, over the selected period or percent of the average over the selected period.
This Maprooms explores the predictability of weather-within-climate variability of rainfall by the state of ENSO.
This map explores the historical probability of seasonal weather-within-climate temperature characteristics given the state of ENSO.
This map explores the historical probability of seasonal average monthly rainfall given the Terciles of IOD.
This map explores the historical probability of seasonal average monthly temperature given the Terciles of IOD.
The Maproom facilitates the exploration of the history of extreme monthly and seasonal rainfall characteristics.
The Maproom facilitates the exploration of the history of extreme monthly and seasonal minimum and maximum temperatures.
Climate Monitoring
The Standardized Precipitation Index is an indicator of extreme rainfall events, whether they are drought or excess rainfall.

This Analysis tool allows users to view different presentations of the the most recent dekad.
Climate Forecast
Calibrated Subseasonal Tercile categories precipitation experimental forecasts issued 1-2 months behind real time.
Subseasonal skill score based on the historical performance of each model and their multi-model ensemble.
This tool displays maps of meteorological drought risk using the standardized precipitation index SPI. It allows the user to choose between maps of either the predicted drought severity for a user-specified likelihood or the risk of a certain magnitude of drought level happening.
