Manoj Joshi is Professor of Climate Dynamics in the School of Environmental Sciences at UEA. He investigates climate change through analysis of models of the present and the past dynamics of the Earth’s climate – including the past ice ages and periods of exceptional warmth over millions of years. He is part of a global project understanding connections between the Arctic, the lower latitudes and the monsoon of the Tibetan Plateau. Key areas are: the climate’s response to radioactive drivers (processes that change the Earth’s climatic energy balance); the warming contrast between land and ocean under climate change; stratospheric processes and climate; the biogeochemical process of the climate and the Earth system.

Manoj also has an interest in planetary science. He has been a Fellow at the NASA Ames Research Center in California, studying the atmosphere and climate of Mars, and contributing to planning for space missions. At that time, he also worked on constructing theoretical and computer-based models to predict the properties of the climates of exoplanets (planets orbiting stars other than the Sun). He spent a year as a scientist at the SETI Institute researching on planetary climates. He has also been a research scientist at the UK’s Met Office.

Oceans have been warming at almost half the rate of land - here's why

World Economic Forum  online


In a 2008 paper, Prof Manoj Joshi – then at the Met Office Hadley Centre and the University of Reading and now at the University of East Anglia – was the first to point out that dynamical processes in the atmosphere connect temperature and humidity over land and ocean regions.

Dusty alien planets could be more likely to harbor life, study suggests  online


However, while dust might be a key factor in some planets' habitability, it also complicates scientists' ability to observe these planets. "Airborne dust is something that might keep planets habitable, but also obscures our ability to find signs of life on these planets. These effects need to be considered in future research," co-author Manoj Joshi, a professor at the University of East Anglia said in the same statement.

Study predicts a significantly drier world at 2ºC

Science Daily  online


New research predicts a significantly drier world if global warming reaches 2ºC. Over a quarter of the world's land could become significantly drier and the change would cause an increased threat of drought and wildfires. Limiting warming to under 1.5ºC would dramatically reduce the fraction of the Earth's surface that undergoes such changes. Areas which would most benefit from keeping warming below 1.5ºC include Central America, Southern Europe, Southern Australia, parts of South East Asia, and Southern Africa.

Dr. Manoj Joshi, from UEA’s School of Environmental Sciences, said: “On Earth, we have a circulation where warm water moves towards the poles at the surface, before being cooled, then sinking at high latitudes and travelling towards the equator at depth.

"We only looked at winter, as this is when the jet stream is strongest, but we will look at other seasons in the future," said co-author Manoj Joshi, a lecturer in climate dynamics from the University of East Anglia.

The Influence of Atlantic Variability on Asian Summer Climate Is Sensitive to the Pattern of the Sea Surface Temperature Anomaly | Journal of Climate


We simulate the response of Asian summer climate to Atlantic multidecadal oscillation (AMO)-like sea surface temperature (SST) anomalies using an intermediate-complexity general circulation model (IGCM4). Experiments are performed with seven individual AMO SST anomalies obtained from CMIP5/PMIP3 global climate models as well as their multimodel mean, globally and over the North Atlantic Ocean only, for both the positive and negative phases of the AMO.

UK Climate Projections: Summer daytime and night-time urban heat island changes in England’s major cities | Journal of Climate


In the UK where 90% of residents are projected to live in urban areas by 2050, projecting changes in urban heat islands (UHIs) is essential to municipal adaptation. Increased summer temperatures are linked to increased mortality. Using the new regional UK Climate Projections, UKCP18-regional, we estimate the 1981–2079 trends in summer urban and rural near-surface air temperatures, and UHI intensities during day and at night in the 10 most populous built-up areas in England.

Mineral dust increases the habitability of terrestrial planets but confounds biomarker detection | Nature


Identification of habitable planets beyond our solar system is a key goal of current and future space missions. Yet habitability depends not only on the stellar irradiance, but equally on constituent parts of the planetary atmosphere. Here we show, for the first time, that radiatively active mineral dust will have a significant impact on the habitability of Earth-like exoplanets.
